What is the name of this hypothesis test? A random sample of 20 independent female college-aged dancers was obtained, and their heights (in inches) were measured. The average height of the 20 dancers was 63.2 inches with a standard deviation of 2.6. Some people claim that the physical demands on dancers are such that dancers tend to be shorter than the typical person in the population. Test the hypothesis that dancers have a smaller population mean height than 64.5 inches.
