Questions 38-44 relate to z scores. Sociology researchers Pam and Ale G, were interested in studying trends in human body temperatures affected by social inequality. The latest world data shows an average body temperature of around 98o F.

The couple selected a sample of 135 Chaffey College students showing a sample mean of 98o F., and a standard deviation of 10. Convert x = 89 to a z score. 1 -0.9 0.9

Question 40 2 / 2 pts What is the probability that a student will report a body temperature of 99 degrees or higher?

z score=
