Question

to describe the sampling distribution from a popuation that is skewed right with mean 70 and standard deviation 15. Jack obtains 1000 random inds the mean of the means, and determines the standard deviation of the means Diane does the same simulation, but obtains 1000 random samples of size n 30 from the population. Complete parts (a) through (e) below Ο A lah dihibution expected to be skewed left but rot as much as the original dtrbution Diane's dstbution iscopo ted to be approïnately normal. O B. Jack's dstitution and Dane's distribution are expected to be apprornately normal. However Jack's wl have a greater standard deviation O C. Diane's O D. Jack's distribution is expected to be skewed right, but not as much as the original distribution Diane's distribution is expected to be approximately normal. (b) What do you expect the mean of Jack's distribution to be? What do you expect the mean of Dianes distribution to be? s expected to be skewed right, but more than the original O A. Jack's distribution is expected to have a mean of 31.3. Diane's distrbution is expected to have a mean of 70 O B. Jack's O C. Jack's distribution is expected to have a mean of 31.3. Diane's distribution is expected to have a mean of 128 O D. Both Jack's distribution and Diane's distribution are expected to have a mean of 70 (e) What do you expect the standard deviation of Jack's distribution to be? What do you expect the standard deviation of Diane's distribuion to be? is expected to have a mean of 70. Diane's distribution is expected to have a mean of 12.8. O A. Jack's distribution is expected to have a standard deviation of 6.7. Dianes distibution is expected to have a standard deviation of 15 OB. Both Jack's Ос. Jack's distribuson is expected tohave a standard dev aton of 6 7. Dane's distribution is expected to have a stadard deviation of 2.7 O D. Jacks distribution is expected to have a standard deviation of 15. Diane's distribution is expected to have a standard deviation of 2.7 to have a standard deviation of 15
