Suppose we are trying to calculate a 98% confidence interval for
a population mean height of adult
females in the United States. To do this, we use a sample of size
64 females. From that sample, we get a sample mean of 108 cm and a
sample standard deviation of 23.5 cm. What critical number do we
need to use to make this confidence interval? Round your
answer to 3 decimal places.
