Your company sells exercise clothing and equipment on the Internet. To design the
clothing, you collect data on the physical characteristics of your different types of
customers. We take a sample of 74 male runners and find their mean weight to be 62.19
kilograms. Assume that the standard deviation is s = 4.5. Using internet research you see
that the averaged male weight should be 61.3 kg. You want to see if there is evidence to
suggest the average male weight is different than 61.3 kg.
What kind of test is this?
