Do the data provide significant evidence at 3.5% level that population mean response after attending the presentation is larger than 4.7 There are 258 students Sample mean response 4.98 Sample standard deviation 1.62 Do the data provide significant evidence at 3.5% level that population mean response after attending the presentation is larger than 4.7 There are 258 students Sample mean response 4.98 Sample standard deviation 1.62 There are 258 students Sample mean response 4.98 Sample standard deviation 1.62 Solution Formulating the null and alternative hypotheses, Ho: u <= 4.7 Ha: u > 4.7 As we can see, this is a right tailed test. Thus, getting the critical z, as alpha = 0.035 , alpha = 0.035 zcrit = + 1.811910673 Getting the test statistic, as X = sample mean = 4.98 uo = hypothesized mean = 4.7 n = sample size = 258 s = standard deviation = 1.62 Thus, z = (X - uo) * sqrt(n) / s = 2.776213551 Also, the p value is p = 0.002749804 As z > 1.8119 (or, P < 0.035), we REJECT HO. Thus, there is significant evidence that the population mean response after attending the presentation is larger than 4.7. [CONCLUSION].

1. Explain why cholesterol needs to be transported in the blood in lipoprotein particles.
Thanks!! Ill ullallisill for the genetic material- What did they 5. are carried in the circulation in
water (blood) soluble rotein particles that consist of a hydrophobic core consisting mainly of
esterified cholesterol and triglycerides, and a hydrophilic surface of mainly unesterified
cholesterol, phospholipids and apolipoproteins Explain why cholesterol needs to be transported
in the blood in lipoprotein particles.
Solution
Cholesterol needs to be transported in the blood in lipoprotein particles because cholesterol is a
non polar substance and is therefore insoluble in water.For cholesterol to be transported through
plasma, it has to be associated with different lipoprotein molecules
