42 of 50 Random samples of size 225 are drawn from a population with mean 100 and standard deviation 20. Find the mean and standard deviation of the distribution of sample means. OHX = 225, ox = 20 O HX = 100, ox = 29 O HX = 100, ox = 1.33 O uX = 11.25, ox = 5 43 of 50 The empirical rule is used to show approximate proportions of data included in specific areas under the normal curve.
