Chemists use pH to measure the acid/alkaline nature of compounds. A large vat of mixed commercial chemicals is supposed to have a mean pH= 6.3 with a standard deviation s = 1.9. Assume a normal distribution for pH values. If a random sample of 10 readings in the vat is taken and the mean pH is computed, find the probability that the mean is between 5.2 and 7.1?.

In a document, Answer the questions below and submit a screenshot of the commands you ran, in the terminal, for each task. Task 1: A file called animals.csv (in the shell-lesson-data/exercise-data/animal-counts folder) contains data, Task 2: Consider the following command: cut -d , -f 2 animals.csv The cut command is used to remove or cut out certain sections of each line in the file, and cut expects the lines to be separated into columns by a Tab character. A character used in this way is a called a delimiter. In the example above we use the -d option to specify the comma as our delimiter character. We have also used the -f option to specify that we want to extract the second field (column).

Draw a swim-lane activity diagram for the above scenario. A business wants to create an application to partially automate its hiring process. The candidate must pass several stages before being hired by this company. Initially, a candidate will create an application using the app. The applicant's application will be reviewed by the recruitment team after it has been submitted. If the recruiter is interested in the application, a test will be administered online via the application. The hiring staff may, however, bypass the online test and schedule an interview instead for excellent candidates with more experience. After appearing on the online test if and only if the score is greater than or equal to 80% then the recruitment team will schedule an interview for the applicant. The interviewer will conduct an interview with the candidate. If the candidate passes the interview the recruitment team will prepare an offer and fix a salary for the candidate concurrently. The candidate after reviewing the offer can either accept or reject the offer. If the candidate chooses to accept it then the recruitment team will hire the candidate. On the other hand, the recruiter may reject the application while reviewing it, if the online test result is below 80%, or if the interviewer decides against the candidate after the interview. Draw a swim-lane activity diagram for the above scenario..
