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 42.4 fluid ounces and a standard deviation of 5.6 fluid ounces. You randomly sample 30 people and record the weekly milk consumptions shown below. 35 49 31 35 40 43 31 54 35 460 ent 39 27 38 49 39 42 39 45 44 43 38 31 27 39 51 39 45 39 49 35 us . . . . .

The standard deviation is (Round to one decimal place as needed.) {o} Compare the mean and standard deviation of your sample with those of the previous study. Discuss the dilt'erenoes. The sample mean is E than the previous mean, so, on average, consumption from the sample is E than in the previous study. The sample standard deviation is E than the previous standard deviation by D so the milk consumption is E spread out in the sample. StatCrunch
