1) Suppose a researcher is interested in understanding the variation in the price of store brand milk. A random sample of 36 grocery stores selected from a population and the mean price of store brand milk is calculated. The sample mean is $3.13 with a population standard deviation of $0.23. Construct a 92% confidence interval to estimate the population mean. 2) Construct 90%, 95%, and 99% confidence intervals to estimate μfrom the following data. State the point estimate. Assume the...
