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 47.4 fluid ounces and a standard deviation of 11.1 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 42 56 34 37 46 51 32 66 40 51 D 45 26 40 58 44 43 45 53 51 49 42 31 25 46 64 46 51 45 59 40 (a) Draw a frequency histogram to display these data.

Question
The sample mean is Greater/Less than the previous mean, so, on average, consumption from the sample is Greater/Less than in the previous study. The sample standard deviation is Greater/Less than the previous standard deviation by _____ so the milk consumption is More/Less spread out in the sample.
Above is the complete question for the last question of the problem that I attached below.

C. No, because the histogram is neither symmetric nor bell-shaped.
D. No, because the histogram is symmetric and 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.
