Can you please assist with the following questions?Problem 1A professor is interested in comparing the characteristics of students that vote compared to students that do not vote in elections. She decided to compare the CPA (grades) of students. For a random sample of 115 students that reported they had voted in the previous elections she found a mean CPA of 2.78 and a standard deviation of 0.56. For an independent sample of 123 students who had not voted, she found a mean CPA of 2.74 and standard deviation 0.63. Test at the 5% level of significance if in general the mean CPA of students who vote is higher than the CPA of students that do not vote.Problem 2We are examining job changes among employees and collect data for a random sample of 25 males and a sample of 16 females. For the sample of male employees the mean number of job changes was 2.91 with a standard deviation of 1.32, while for female employees the mean number of job changes was 1.21 with a standard deviation of 0.53. Test if in general women employees change on average fewer job positions compared to men employees. Use a 1% level of significance.
