Pulse rates of adult men are approximately normal with a mean of 70 and a standard deviation of 8 . Which choice correctly describes how to find the proportion of men that have a pulse rate greater than 78?
a. Find the area to the left of z = 1 under a standard normal curve.
b. Find the area between z = -1 and z = 1 under a standard normal curve.
c. Find the area to the right of z =1 under a standard normal curve.
d. Find the area to the right of z = -1 under a standard normal curve.
Question 2
For each study, decide if the two samples are independent samples or paired samples. A study compared the average number of courses taken by a random sample of 100 freshmen at a university with the average number of courses taken by a separate random sample of 50 freshmen at a community college.
a. Independent samples
b. Paired samples
