According to the Bureau of Labor Statistics, 15% of the U.S. workers were government employees. A researcher is surveying 125 individuals to comment on perceived waste of tax dollars by the government. The researcher doesn’t want too many government employees in the survey, so considers limiting the survey to at most 10% of the 125 individuals in the sample.

Let p ˆ be the proportion of the 125 individuals who are government employees.

What is the sampling distribution of p ˆ ? Include shape, center and spread of the distribution. Round answers to 3 places past the decimal if necessary.

Shape: Normal May or may not be normal

Center=                                                  Spread=
