A recent television news station reports that the average Body Mass Index (BMI) (a measure of a person’s body composition) for males is 10kg/m2. A local university believes that this is unusually low and suspects that males are actually higher than their claim. They conduct a study with 20 undergraduate males randomly selected from their campus. A sample mean of 16.5kg/m2 with a standard deviation of 3.2kg/m2 was obtained. Using an alpha of.05 is there enough evidence to warrant rejection of the news station’s claim of 10kg/m2?? a. Write your hypotheses for this scenario. b. Is this a one tailed or two tailed test? i. Why? c. What statistical test would be used for this scenario? i. Explain why.

A recent television news station reports that the average Body Mass Index (BMI) (a
measure of a person’s body composition) for males is 10kg/m2. A local university
believes that this is unusually low and suspects that males are actually higher than their
claim. They conduct a study with 20 undergraduate males randomly selected from their
campus. A sample mean of 16.5kg/m2 with a standard deviation of 3.2kg/m2 was
obtained. Using an alpha of.05 is there enough evidence to warrant rejection of the news
station’s claim of 10kg/m2??
a. Write your hypotheses for this scenario.
b. Is this a one tailed or two tailed test?
