using minitab, a random sample of 200, (N(30, 8)).

1. According to the empirical rule, how many of the values do you expect to be less than 14 or greater than 46? Briefly explain your answer.

2.

  1. Since the weights are distributed N(30, 8), we say that we expect the average weight of a sample of farm-raised turkey to be 30 lbs.; that is, 30 is the expected value (also, the mean) of the distribution. What is the average of your sample? Briefly explain (in one word) why it is not exactly equal to 30.

3. What is the standard deviation of your sample? What did you expect the standard deviation of your sample to be? Briefly explain (in one word) why the standard deviation of your sample is not exactly equal to what you expected.

    Use Minitab to simulate taking a random sample of 200 farm-raised turkey       (N(30, 8)). Use Minitab to standardize all of your random numbers, then do a stem-and-leaf diagram of the standardized scores. (Remember, when you know the distribution, you standardize using the mean and standard deviation of the distribution, not of the sample.) Using the stem-and-leaf, state how many of the numbers in your sample actually are less than 14 or greater than 46.
