Let's shake on it: A random sample of 12-ounce milkshakes from 12 fast-food restaurants had the following number of calories. 450 399 591 504 510 613 476 700 473 375 472 642 Send data to Excel Assume the population standard deviation is o =93. Part: 0/ 3 Part 1 of 3 Explain why it is necessary to check whether the population is approximately normal before constructing a confidence interval. It is necessary to check whether the population is approximately normal because (Choose one) the sample size is less than or equal to 30 the sample standard deviation is not known the population mean is not known the population standard deviation is not known
