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 47.8 fluid ounces and a standard deviation of 10.7 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 40 56 34 38 44 53 32 67 41 50 48 26 41 56 45 44 45 51 53 53 42 35 26 45 62 45 50 45 56 41 Y A. Yes, because the histogram is symmetric and bell-shaped. O B. No, because the histogram is symmetric and bell-shaped. O C. No, because the histogram is neither symmetric nor bell-shaped. O D. Yes, because the histogram is neither symmetric nor bell-shaped. (b) Find the mean of your sample. The mean is 45.5 (Round to one decimal place as needed.) Find the standard deviation of your sample. The standard deviation is (Round to one decimal place as needed.)
