How would I find the solution for the following problem in Excel? Suppose we are trying to estimate the average annual salary of all high school teachers in a particular region. After gathering data on 100 teachers, we have determined the sample mean to be $50,000 and the sample standard deviation to be $5,000. What is the t-statistic associated with this sample if information from the government reveals that the actual average salary (the population mean salary) is $49,000?
