Chapter 5: Normal Probability Distributions 38. [APPLET] Milk Consumption You are performing a study about weekly per capita milk consumption. A previous study found weekly per capita milk consumption to be normally distributed, with a mean of 48.7 fluid ounces and a standard deviation of 8.6 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 30 33 37 48 57 40 45 54 41 43 31 47 65 25 39 53 51 58 52 40 40 46 46 44 48 443 69 61 52 52 45 38 47 47 49 57 a.
