I need help with the following statistic lab. When I put the information in an online calculator, I keep getting an error message. I also need help with answering the items in bold. I am not sure what I am missing. Thank you in advance for your help!

According to a 2015 survey of 134,632 psychologists by the American Psychological Association, the average annual salary of psychologists was $100,362. A sample of psychologists in teaching positions (n = 19,904) had an average annual salary of $70,742 with a standard deviation of $24,860.

Use a computer program or online calculator to construct a 95% confidence interval for the annual salary of psychologists in teaching positions.

There is an online confidence interval calculatorfree for use.

Follow the calculator's directions to calculate the confidence interval.

Report the lower and upper limits of the confidence interval in a text statement summarizing the results.

Paste a screenshot of the output of the calculator into a Word or Excel document.
