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??
