Christine Munoz 1 My Blackboard Courses& Organizations OC Student Content Collection d Quiz Assignment (Chapter 7: The Central Limit Theorem) Let X represent the full length of a certain species of newt. Assume that X has a normal probability distribution with mean 40.9 inches and standard deviation 7.2 inches. You intend to measure a random sample of n - 84 newts. The bell curve below represents the distibution of these sample means. The scale on the horizontal axis is the standard error of the sampling distribution. Complete the indicated boxes, correct to two decimal places. 39.32 40.9 42.48 Licens Points possible: 1 Unlimited attempts. Score on last attempt: (0.2, 02, 0. 02.0, Score in gradebook (0.2 0.2, 0, 0.2, 0), Out oft (02,02.02, 02 02) Message instructor about Submit

Explanation / Answer

The scales are = 40.9-2*7.2/sqrt(84) and 40.9+2*7.2/sqrt(84)

                        = 39.33 and 42.47

So, the value on left box should be 39.33

Value on right box should be 42.47
