The Table above shows pre and post medication diastolic blood pressures for a group of 7
men as well as a group of 6 women. Whenever appropriate assume each column is a
sample from a normal distribution.
For all hypotheses testing questions state the hypotheses, find the test statistic, make
a sampling distribution diagram shading the p-value, and then find the p-value in
order to make a decision!](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fd0a6089f-b0c6-439f-aec5-565257fccbe3%2Fdcff42da-6688-4b82-9204-ee207a397ef8%2Fyed45t_processed.jpeg&w=3840&q=75)
