In each of Exercises, explain the effect on the margin of error and hence the effect on the accuracy of estimating a population mean by a sample mean. Decreasing the sample size while keeping the same confidence level

What is the measurement of X?

You want to estimate the percentage of statistics students who get grades of C or better. How many students should you survey to be 95% confident that the sample percentage is off by no more than 2 percentage points.

A survey of 100 students are taken. 32 Yes and 68 no. Find the point estimate of p and 96% CI.

Use the expression in the accompanying discussion of sample size to find the size of each sample if you want to estimate the difference between proportions of men and women who own smartphones. Assume that you want 90% confidence that your error is no more than 0.035. A Click the icon to view the discussion of sample size. The sample should include men and women. (Type whole numbers.)
