You work for a large retailer and have been asked to estimate
the proportion of your customers that are less than 30 years old.
You have sampled a large number of stores and have found that of
the 192 customers you have surveyed, 88 are less than 30 years
old.
Assuming your sample is valid, what is the lower bound of a 95%
confidence interval for the population proportion of customers who
are less than 30 years old?
(Report your answer as a decimal and not as a percentage. For
example, report 0.052 rather than 5.2%.)
