(in general, you must first prove that assumption, though.)construct a 90% confidence interval for the population mean grams of fat per serving of chocolate chip cookies sold in supermarkets. i. state the confidence interval. (round you answers to two decimal places.)ii. sketch the graph. iii. calculate the error bound. (round your answer to two decimal places.)
