A. Construct a 90% confidence interval estimate for the population proportion of employees who said that they are rules that they stay connected.

Explanation / Answer

Z=(p-P)/[(PQ)/n]=(.6732-.1645)/(4.1118)=.5087/2.0277=.2509. And Z table value at 90% is 1.645, Zcal<Ztab, so we accept that the population proportion of employees who said that they are rules that they stay connected. The 90% confidence interval estimate for the population proportion of employees who said that they are rules that they stay connected is (-2.8269,3.8443).
