Question

We would like to determine the mean value for a population. Given that the a sample of size 100 has a mean of 5 and the population standard deviation is \sigma=4, find the 95\% confidence interval. NOTE: Enter only the upper bound. For example, if the interval is (20.7, 32.8), then you should enter only 32.8 as your answer.

Step 1

The standard error of the mean (SEM) is calculated using the formula: SEM = population standard deviation / square root of sample size Given that the population standard deviation is g-4 and the sample size is 100, we can calculate the SEM as follows: SEM = Show more…
