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 leheto 26.5 625 265 62 5 26.5 62.5 62.5 26.5 62.5 Volume Volume Volume Volume Do the consumptions appear to be normally distributed? Explain. Choose the correct answer below. O A. No, because the histogram is neither symmetric nor bell-shaped. O B. Yes, because the histogram is neither symmetric nor bell-shaped. OC. No, because the histogram is symmetric and bell-shaped. &D. Yes, because the histogram is symmetric and bel-shaped. (b) Find the mean of your sample. The mean is 43.9 (Round to one decimr Find the standard dev le. The standard deviatic greater (Round to one decimi less (c) Compare the mea riation of your sample with those of the previous study. Discuss the differences. The sample mean is than the previous mean, so, on average, consumption from the sample is than in the previous study. The sample standard deviation is than the previous standard deviation by, so the milk consumption is spread out in the sample.
