You are conducting a study to see if students do better when they study all at once or in intervals. One group of 12 participants took a test after studying for one hour continuously. The other group of 12 participants took a test after studying for three twenty minute sessions. The first group had a mean score of75 and a variance of 120. The second group had a mean score of 86 and a variance of 100. a. What is the calculated t value? Are the mean test scores of these two groups significantly different at the .05 level? b. What would the t value be if there were only 6 participants in each group? Would the scores be significant at the .05 level? Solution A) Formulating the null and alternative hypotheses, Ho: u1 - u2 = 0 Ha: u1 - u2 =/ 0 At level of significance = 0.05 As we can see, this is a two tailed test. Calculating the means of each group, X1 = 75 X2 = 86 Calculating the standard deviations of each group, s1 = 10.95445115 s2 = 10 Thus, the standard error of their difference is, by using sD = sqrt(s1^2/n1 + s2^2/n2): n1 = sample size of group 1 = 12 n2 = sample size of group 2 = 12 Thus, df = n1 + n2 - 2 = 22 Also, sD = 4.281744193 Thus, the t statistic will be t = [X1 - X2 - uD]/sD = -2.569046516 [ANSWER, T VALUE] ******************************** b) Calculating the means of each group, X1 = 75 X2 = 86 Calculating the standard deviations of each group, s1 = 10.95445115 s2 = 10 Thus, the standard error of their difference is, by using sD = sqrt(s1^2/n1 + s2^2/n2): n1 = sample size of group 1 = 6 n2 = sample size of group 2 = 6 Also, sD = 6.055300708 Thus, the t statistic will be t = [X1 - X2 - uD]/sD = -1.816590212 [ANSWER] For part A, the P value is p = 0.01750305 For part B, the P value is p = 0.099328388 Hence, Part A would be significant, but part B wouldn\'t.

Write a class named Deque20, placed in the file Deque20.java. It should behave exactly as described in the Java interface Deque (Google: \"Java 8 Deque\") except that it should only implement the following methods: a no-argument constructor, addFirst, addLast, removeFirst, removeLast, peekFirst, peekLast, and size. Your class should not extend or implement any class or interface. It must use an array as its storage, allow generic types (E), and be as efficient as possible. The Deque javadoc mentions several exceptions, but you should only return NullPointerException (if someone tries to add a null reference to the Deque) and NoSuchElementException (if someone tries to remove an item from an empty Deque). Your deque should store objects in a circular array. Probably the simplest implementation has objects with fields The meaning being that the elements currently in the deque are at positions list[first_index], list[(first_index+1)%list.length], list[(first_index+2)%list.length],..., list[(first_index+num_elems-1)%list.length]. The modulus is necessary because first_index might be near the end of the array and adding to it might result in an index that\'s out of bounds. When an add operation would cause the capacity of the array to be exceeded, you should double the size of the array by creating a new array of twice the size and copying the old array contents into the new. Do not worry about ever reducing the size of an array. Also, whenever a reference is removed from your deque, the old array location should be set to null so that the garbage collector knows that the old item is no longer referred to by the deque. Solution public class Deque20 { private int first_index; private int num_elems; private Object[] list; Deque20(){ first_index = 0; num_elems = 0; list = new Object[20]; } private void doubleSize(){ Object[] arr = new Object[2 * list.length]; for(int i = 0; i < list.length; ++i){ arr[i] = list[(i + first_index) % list.length]; } list = arr; } public void addFirst(E val){ if(list.length == num_elems){ doubleSize(); } int index = (first_index + list.length - 1) % list.length; list[index] = val; ++num_elems; } public void addLast(E val){ if(list.length == num_elems){ doubleSize(); } int index = (first_index + num_elems) % list.length; list[index] = val; ++num_elems; } public E removeFirst(){ int index = first_index; E ret = (E) list[index]; first_index = (first_index + 1) % list.length; return ret; } public E removeLast(){ int index = ((first_index + num_elems) % list.length) - 1; E ret = (E) list[index]; --num_elems; return ret; } public E peekFirst(){ return (E) list[first_index]; } public E peekLast(){ int index = ((first_index + num_elems) % list.length) - 1; return (E) list[index]; } public int size(){ return num_elems; } }.

What is Incorporation by Reference? and How is it used in a contract? Solution Incorporation by reference is an act of including second document within the first document by giving only reference in first document. Ie if in first document only a single line is kept giving reference of second document. than the secound document will be part of first document. Incorporation by reference is often done in creating law as well in contract law nad trust and estate law Incorporation by reference is used in contract by way of terms and condition. For example there are general set of terms and condition to contarct now instead of including all the tems and condtion to contract a company can just give reference to it, making it binding to the companies entering the contract. Thus it is very important to read document if it is included by reference.

All of these are examples of evidence used to support the hypothesis of endosymbiosis, EXCEPT:a. Mitochondria and plastids contain circular DNA molecules similar to the circular chromosomes of bacteriab. Mitochondria and plastids, like prokaryotes, only contain genetic material in the form of RNAc. Mitochondria and plastids can replicate themselves in a process similar to prokaryotesd. Mitochondria and plastids have their own ribosomes and enzymes that can be used to transcribe and translate DNA into proteinse. Mitochondria and plastids have a double membrane (inner and outer) Solution Out of the above options , the correct will be B. Mitochondria and plastids a have their genetic material in the form of DNA not RNA. They donot have any such machinary for their expression , so this option is incorrect regarding endosymbiosis. Otherwise rest all the sentenses are true. They have circular genome like Prokaryotes, and can replicate and also have double membrane layer..

Tim would like to compare the climate of Sydney. Australia. to the climates of the other 3 cities. He collects data for the day of the year t and the average daily high temperature H in degrees Fahrenheit. As before, t = 0 represents January 1, and t = 364 represents December 31. Use your graphing calculator to perform a sinusoidal regression on the data. Write the function in the form a sig (bt + c)+ d. Round of a and d to 2 decimal places , and b and c to 4 decimal places. Circle the letters(s) of all statements that would accurately describe the climate of Sydney in comparison to the other cities. Remember that summer in the Southern Hemisphere is the months of December. January, and February. Similar temperature to Buenos Aires, but hotter in the summer. Similar temperature to Buenos Aires, but cooler in the summer. Cooler than Osaka, but more variable. About as variable as Los Angeles, but generally cooler. Warmer than Los Angeles, but not as variable. none of these What if Sydney\'s climate were equally as variable as Osaka\'s? Rew ntc the function for Sydney to account for this new variability, and complete the missing values in the table Give temperatures to the nearest tenth of a degree. Solution 31) Sydney climate is equally variable as Osaka So the maximum and minimum variation of temperature for Sydeny shall be same as of Osaka. So we make the the amplitude of sin function of Sydney(20.71) , same as of Osaka and vertical shifting of Sydney same as of Osaka( +68.97) H(t) = 20.71 sin (.0172t + 89.7420) + 68.97 Now plugging t = 15 H(t) = 20.71 sin ( .0172*15 + 89.7420) + 68.97 H = 90 degrees for t = 74 H(t) = 20.71 sin ( .0172*74 + 89.7420) + 68.97 H = 90 degrees for t = 135 H(t) = 20.71 sin ( .0172*135 + 89.7420) + 68.97 H = 89.60 degrees for t = 196 H(t) = 20.71 sin ( .0172*196 + 89.7420) + 68.97 H = 89.60 degrees for t = 258 H(t) = 20.71 sin ( .0172*258 + 89.7420) + 68.97 H = 89.60 degrees.

Show that the function T : R^2 rightarrow R^2 given by T(x, y) = (-y, x) is a linear transformation. Solution T: R2 R2 is given by T(x,y) = ( -y,x). Let (a,b), (c,d) be two arbitrary elements of R2 and let be an arbitrary scalar. Then T[ (a,b) + (c,d)] = T( a+c, b+d) = (-b-d, a+c)= (-b,a) + (-d,c) = T(a,b) + T(c,d). Thus T is closed under addition. Further, t[ (c,d)] = T(c , d) = (-d, c) = ( -d, c) = T (c,d). Thus T is closed under scalar multiplication. Therefore, T is a linear transformation..
