The researchers want an estimate (or inferred value) for the mean spending and its likely range for the entire population. a) (5 points) Estimate the range in which we expect to find the population mean for spending by constructing a confidence interval. This must be done BY HAND. Round to 4 decimal places and show all your work. Assume the population standard deviation is 16. Use a 95% confidence level. Provide the appropriate values on the lines below.
