In a simple random sample of 200 workers, 23.0 percent stated that they aspire to have their boss’s job.             How many of the 200 workers sampled aspire to have their boss’s job?   2.   To the 95 percent confidence level, find the confidence interval estimate of all workers who aspire to have their boss’s job. Can we safely assume that less than 30% of all workers aspire to have their boss’s job?    3.  If we wanted to reduce the margin of error to 4 percent, how big would our sample size have to be (again to the 95 percent confidence level)?
