Q5 a) Demographic data from 126 countries is obtained for the year 2017. It is hypothesized that life expectancy (Y) is dependent on number of under five deaths (X2) , polio immunization coverage (D), Per capita Govt. Exp. on Health Care (X3) (in Rs crores), Per Capita GNI (in Rs crores) (X4) and Average number of years of Schooling (Xs). Polio immunization coverage =1 if yes and 0 otherwise.

An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on average, to finish their undergraduate degrees. Dr. Lewis believes the mean time for students at Clayton State University is longer than this average. A survey of 49 graduates from Clayton State had a mean time of 5.1 years to complete their Bachelor's degree, with a sample standard deviation of 1.2 years. Correctly identify the null and alternative hypotheses for this study:
one hundred adults who had their Type 1 or Type 2 diabetes were selected to determine if the inhalable version of insulin is able to manage blood sugar 'vels just as swell as injected insulin. The adults uses the inhaler for 3 months and then their blood sugar levels were recorded. Then they uses the injection for 3 months and then their blood sugar levels were also recorded. If we want to test if there is a difference in .average blood sugar levels using the two methods ?Which inference procedure should we use [Hint: test statistics ] None of these .A O Confidence interval about the population mean of the secondgroup .B O t-test about the difference between two means for independent samples CO t-test about the mean difference for paired samples .D O Confidence interval about the population mean of the first group .E O

4. Captopril is a drug designed to lower systolic blood pressure. When subjects were treated with this drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. Results are given in the accompanying table (based on data from “Essential Hypertension: Effect of an Oral Inhibitor of Angiotensin-Converting Enzyme”, by MacGregor et al., BMJ, Vol. 2). Using a 0.01 significance level, is there sufficient evidence to support the claim that captopril has an effect on systolic blood pressure? Explain why statistical methods from Z-interval, Z-test, T-interval or T-test –cannot be used for this problem. Then, use the sign test to conduct the required test in R studio. Please show your work.
