An economist would like to estimate the 95% confidence interval for the average real estate taxes collected by a small town in California. In a prior analysis, the standard deviation of real estate taxes was reported as $1,580. What is the minimum sample size required by the economist if he wants to restrict the margin of error to $500

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.
