a. With the discrete sampling option, select one hundred samples of size 30 from the population of waits. (It is necessary to assign a probability of 1/832 to each of the 832 waits before drawing the samples. This probability should appear in Column C). Be sure to generate a random seed using =RAND().
b. Calculate the mean, standard deviation, and standard error of each of the one hundred samples.
c. Generate a frequency distribution of the means of the one hundred samples, based on one standard deviation units around the mean of all sample means.
d. Display the resulting frequency distribution in a column graph and give some interpretation as to whether the distribution looks approximately normal or not.
