With the discrete sampling option, select 250 samples of size 100 from the population of women. Be sure to generate a random seed using =RAND ( ) . b. Calculate the mean, standard deviation, and standard error for each of the 250 samples. c. Generate a frequency distribution of the means of the 250 samples, based on 1 standard deviation unit around the mean of all sample means. d. Display the resulting frequency distribution in a column graph, and give some inter- pretation as to whether the distribution looks approximately normal. e. Save this file for later use
