An economist wants to estimate the mean per capita income (in thousands of dollars) for a major city in California. Suppose that the mean income is found to be $20.7 for a random sample of 1301 people. Assume the population standard deviation is known to be $6. Construct the 98% confidence interval for the mean per capita income in thousands of dollars. Round your answers to one decimal place.
