Many companies have started to feature female models who are not the traditional thin women who have graced magazine covers for the last 20 to 25 years.

Suppose Calvin Klein conducted a survey of 1,000 women in which 91% of the respondents said they were satisfied with what they see in the mirror. The managers would like to use these data to develop a 90% confidence interval estimate for the true proportion of all women who are satisfied with their bodies. Develop and interpret the 90% confidence interval estimate.
