Members of a bowling league play thousands of combined games over the course of a season. Suppose that the scores of individual games have
a known standard deviation of o = 30 pins. Daisy plans on taking a
random sample of n games from this population to make a
95% confidence interval for the mean score. She wants the margin of
error to be no more than 10 pins.
Which of these is the smallest approximate sample size required to
obtain the desired margin of error?
