You desire to estimate p for a binomial process. You know that p is less than 0.65 and greater than 0.45. Find n, the sample size required, to yield 95% confidence of estimating the true proportion, p, within .02.

Please show all work!

Solutions

Expert Solution

Given that  p is less than 0.65 and greater than 0.45. hence the sample proportion

and E=0.02 also the Z value at 95% confidence level is 1.96 which is computed using Z table shown below

So, minimum sample is calculated as

You want to know the percentage of utility companies that earned revenue less than 39 million or more than 81 million dollars. If the mean revenue was 60 million dollars and the data has a standard deviation of 13 million, find the percentage. Assume that the distribution is normal. Round your answer to the nearest hundredth.
