I need to have this done within half hour. Thank YOU!:)

17. Minnesota Department of Health wants to test the claim that variability in COVID-19 within Minnesota is greater than 12.75. For this, they took a sample of 25 days data and found that the mean is 215 and standard deviation was 14.17. At alpha=5% what will be the decision?

Question 17 options:

	Reject H0 at alpha =5%
	Do not reject H0 at alpha=5%
	We do not have enough information to make decision

21. To test the claim that mean weight is not equal to 156.3 lbs., a sample of 14 people showed that the sample mean was 172.55 and the sample standard deviation (s) was found to be 26.33 lbs. Find the p value for this test (note that population standard deviation sigma is unknown so that this is t-test).
