A population consists of three housing units, where the number of rooms in each unit is 2, 2 and 4, respectively. a] Represent the population distribution of the number of rooms in a histogram. b] Find the mean and standard deviation of the population distribution. A random sample with replacement of 2 housing units is picked from the population. c] Represent the sampling distribution of sample mean in a histogram. (1) Find the mean of the sampling distribution of sample mean and compare it with the mean of the population distribution. Now, a random sample without replacement of 2 housing units is picked from the population. e] Represent the sampling distribution of sample median in a histogram. f] Represent the sampling distribution of sample standard deviation in a histogram
