E Quiz: Chapter 5 Quiz Question 1 of 10 This quiz: 50 point(s) possible This question: 5 point(s) possible Submit quiz 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 38.5 fluid ounces and a standard deviation of 5.4 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 32 43 26 32 34 40 28 49 32 38 5 34 23 32 44 34 34 34 41 40 39 32 29 22 34 49 34 38 34 42 30 (a) Draw a frequency histogram to display these data. Use seven classes. Choose the correct answer below. DA. O B. O C. OD. O O Frequency Frequency Frequency Frequency ITTTT 235 47 5 35 47 5 475 Volume Volume Volume Volume Do the consumptions appear to be normally distributed? Explain. Choose the correct answer below. O A. Yes, because the histogram is neither symmetric nor bell-shaped O B. No, because the histogram is symmetric and bell-shaped O C. Yes, because the histogram is symmetric and bell-shaped O D. No, because the histogram is neither symmetric nor bell-shaped. (b) Find the mean of your sample. The mean is (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.) (c) Compare the mean and standard deviation 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
