In one of the studies, 1001 adults were interviewed by telephone and asked about their hand-washing habits. In the other study, the hand-washing behavior of 6076 adults was inconspicuously observed within public restrooms in four U.S. cities. Address the following: a.

Use this result to obtain a point estimate for the proportion of adults who say they always wash their hands in public restrooms. b. Verify that the requirements for constructing a confidence interval for p from part (a) are satisfied. c. Using the results from the telephone interviews, construct and interpret a 95% confidence interval for the proportion of adults who say they always wash their hands in public restrooms. d. Is it…
