Let's shake on it: A random sample of 12-ounce milkshakes from 13 fast-food restaurants had the following number of calories. 580 473 Send data to Excel Part 1 of 3 375 591 Assume the population standard deviation is a-91. It is 476 399 400 642 450 510 504 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 the sample size is less than or equal to 30 450 Part 2 of 3 Following is a dotplot of these data. Is it reatonable to assume that the population is approximately normal? 500 700 608 550 650 472 700 ▼reasonable to assume that the population is approximately normal, 传橱国连自己网 al
Part 2 of 3 Following is a dotplot of these data. Is it reasonable to assume that the population is approximately normal? It is 400 Part: 2/3 Part 3 of 3 450 500 550 600 650 700 reasonable to assume that the population is approximately normal. If appropriate, construct a 99.8% confidence interval for the mean calorie count for all 12- ounce milkshakes sold at fast-food restaurants. Round the answers to at least two decimal places. A 99.8% confidence interval for the mean calorie count for all 12-ounce milkshakes sold at fast-food restaurants is 441.54 << 644.30
