In an article by Laroche et al. (The Journal of the American Board of Family Medicine 2007;20:9-15), the average daily fat intake of U.S. adults with children in the household is 91.4 grams, with a standard deviation of 93.25 grams. These results are based on a sample of 3714 adults. Suppose that these results hold true for the current population distribution of daily fat intake of such adults and that this distribution is strongly skewed to the right. Let be the average daily fat intake of 24 randomly selected U.S. adults with children in the household. Find the mean and the standard deviation of the sampling distribution of . Round your answers for standard deviation to three decimal places. Mean = i Standard deviation = i Do the same for a random sample of size 80. Mean = i Standard deviation = i

In an article by Laroche et al. (*The Journal of the American Board of Family Medicine* 2007;20:9–15), the average daily fat intake of U.S. adults with children in the household is 91.4 grams, with a standard deviation of 93.25 grams. These results are based on a sample of 3714 adults. Suppose that these results hold true for the current population distribution of daily fat intake of such adults and that this distribution is strongly skewed to the right. Let \(\bar{x}\) be the average daily fat intake of 24 randomly selected U.S. adults with children in the household. Find the mean and the standard deviation of the sampling distribution of \(\bar{x}\).

Round your answers for standard deviation to three decimal places.

Mean = [ ]
Standard deviation = [ ]

Do the same for a random sample of size 80.

Mean = [ ]
Standard deviation = [ ]
