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 47.5 fluid ounces and a standard deviation of 10.9 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 36 55 30 40 42 49 32 65 38 48 43 27 39 54 44 46 45 53 51 50 36 31 24 45 60 44 50 46 58 36 10- 10- 10- 8- 8 6- 4- 2- 62.5 62.5 26.5 Volume 26.5 26.5 62.5 26.5 62.5 Volume Volume Volume Do the consumptions appear to be normally distributed?
