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 fuid ounces and a standard deviation of 10.9 fuid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 36 55 30 40 42 49 32 65 38 48 O 43 27 39 54 44 46 45 53 51 50 36 31 24 45 60 44 50 46 58 36 (a) Draw a frequency histogram to display these data.
