Is there a difference in the proportion of construction workers who are under 35 years of age and the proportion of telephone repair people who are under 35 years of age? Suppose a study is conducted in Calgary, Alberta, using random samples of 339 construction workers and 285 telephone repair people. The sample of construction workers includes 297 people under 35 years of age and the sample of telephone repair people includes 197 people under that age. Use these data to construct a 90% confidence interval to estimate the difference in proportions of people under 35 years of age among construction workers and telephone repair people.

Is there a difference in the proportion of construction workers who are under 35 years of age and the proportion of telephone repair
people who are under 35 years of age? Suppose a study is conducted in Calgary, Alberta, using random samples of 339 construction
workers and 285 telephone repair people. The sample of construction workers includes 297 people under 35 years of age and the
sample of telephone repair people includes 197 people under that age. Use these data to construct a 90% confidence interval to
estimate the difference in proportions of people under 35 years of age among construction workers and telephone repair people.
