You are planning on applying to the Knirhsdaeh institute as a psychology counselor. They hire millions of psychologists around the world. You know the standard deviation for the salaries is $13 k. To find the average, you sample 18 random employees and get an average salary of $65 k. Find an 92% confidence interval for the true average salary of Knirhsdaeh employees. Use 2 decimal places
