A survey of a representative sample of 478 U.S. employers determined that 359 ranked stress as their top health and productivity concern (globenewswire .com/news release/2016/06/29/852338/0/en /Seventy-five-percent-of-U-S-employers-say-stress -is-their-number-one-workplace-health-concern .html?print=1, June 29, 2016, retrieved May 4, 2017).

a. Use the accompanying output from the ?Bootstrap Confidence Interval for One Proportion? Shiny app to report a 95% bootstrap confidence interval for the proportion of all U.S. employers who would rank stress as their top health and productivity concern. Interpret the confidence interval in context.

b. A number of international employers were also surveyed. If the international employers had a similar rate of identifying stress as their top health and productivity concern, and if the results from international employers were included in the sample, would the width of the resulting confidence interval remain the same, decrease, or increase? Explain.
