Use the given categorical data to construct the relative
frequency distribution.
Natural births randomly selected from four hospitals in a highly
populated region occurred on the days of the week (in the order of
Monday through Sunday) with the frequencies 52, 64, 72, 55, 57, 45,
55. Does it appear that such births occur on the days of the week
with equal frequency?
Construct the relative frequency distribution.

Refer to the data set of 20 randomly selected presidents given
below. Treat the data as a sample and find the proportion of
presidents who were taller than their opponents. Use that result to
construct a 95% confidence interval estimate of the population
percentage. Based on the result, does it appear that greater
height is an advantage for presidential candidates? Why or why
not?
