A.)

A medical researcher is studying the effects of a drug on bloodpressure. Subjects in the study have their blood pressure taken atthe beginning of the study. After being on the medication for 4weeks, their blood pressure is taken again. The change in bloodpressure 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 drugincreases blood pressure. At the end of 4 weeks, 36 subjects in thestudy had an average change in blood pressure of 2.4 with astandard deviation of 4.5.

Find the p-value for the hypothesis test. ___________

Your answer should be rounded to 4 decimal places.

B.)

Find the p-value for the hypothesis test. A random sample ofsize 54 is taken. The sample has a mean of 426 and a standarddeviation of 82.

H0: µ = 400

Ha: µ ? 400

The p-value for the hypothesis test is . ________________

Your answer should be rounded to 4 decimal places.

C.)

Child Health and Development Studies (CHDS) has been collectingdata about expectant mothers in Oakland, CA since 1959. One of themeasurements taken by CHDS is the weight increase (in pounds) forexpectant mothers in the second trimester.

In a fictitious study, suppose that CHDS finds the averageweight increase in the second trimester is 14 pounds. Suppose alsothat, in 2015, a random sample of 43 expectant mothers have meanweight increase of 16.2 pounds in the second trimester, with astandard deviation of 5.7 pounds.

A hypothesis test is done to see if there is evidence thatweight increase in the second trimester is greater than 14pounds.

Find the p-value for the hypothesis test._____________________

The p-value should be rounded to 4 decimal places.

I need to know how to do these with excel but regular wayworks too if its too much.
