Suppose also that, in 2015, a random sample of 34 expectant mothers have mean weight increase of 15.9 pounds in the second trimester, with a standard deviation of 6.2 pounds. A hypothesis test is done to see if there is evidence that weight increase in the second trimester is greater than 14 pounds. Find the p-value for the hypothesis test. The p-value should be rounded to 4 decimal places. Dean Halverson recently read that full-time college students study 20 hours each week. She Type numbers in the boxes decides to do a study at her university to see if there is evidence that students study an average 10 points of less than 20 hours each week.

It was found that he average number of hours that the 35 students studied each week was 18.5 hours. The sample standard deviation of 4-3 hours. Find the p-value. The p-value should be rounded to 4-decimal places A medical researcher is studying the effects of a drug on blood pressure. Subjects in the study Type numbers in the boxes, have their blood pressure taken at the beginning of the study. After being on the medication for to points 4 weeks, their blood pressure is taken again. The change in blood pressure is recorded and used in doing the hypothesis test Change: Final Blood Pressure - Initial Blood Pressure The researcher wants to know if there is evidence that the drug affects blood pressure. At the end of 4 weeks, 31 subjects in the study had an average change in blood pressure of 2.7 with a standard deviation of 5-3. Find the p-value for the hypothesis test. Your answer should be rounded to 4 decimal places
