Need help with the one marked with a red "x"

Suppose that a popular museum is interested in estimating the average age of summer visitors. A random sample of summer visitors is selected. The data is recorded in tab "Age" The researchers want to determine a 95% confidence interval around the mean weight of all summer visitors Required: Determine the following: Mean 38.3125 Standard Deviation 13.41986371 Standard Error 2.372319158 Sample Size 32 t-Value 2.039513446 2.3723 4.838376822 Margin of Error without using Confidence.t 5 Now compute the Margin of Error using Confidence. 3 3 Upper Bound Confidence interval 43.15087682 Lower Bound Confidence interval 33.47412318 Suppose that a popular museum is interested in estimating the average age of summer visitors.
