Data Analysis, please show all work

The amount of yearly rainfaill in Chicago was sampled. 40 years from the records was randomly checked. The mean rainfaill was 33.98 in ches, with a standard deviation of 5.22 inches.

Provide 90%, 95%, and 99% confidence intervals for these values. Remember to provide your answer in the form of a properly phrased confidence interval statement.
Suppose the sample size was doubled. How would this affect the confidence interval? You don't have to provide a quantitative answer here. Simply indicate if it would go up, down, or remain approximately the same.

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
