Question

Suppose Diane and Jack are each attempting to use a simulation to describe the sampling distribution from a population that is skewed left with mean 60 and standard deviation 10. Dane obtains 1000 random samples of siren from the population, finds the mean of the means, and determines the standard deviation of the means Jack does the same simulation, but obtain 1000 random samples of size n-35 from the population Complete parts(a) tough (c) below (a) Describe the shape you expect for Diane's distribution of sample means. Describe the shape you expect for Jack's distribution of sample means. Choose the correct answer below. O A. Dane's distribution is expected to be skewed left, but not as much as the originaldatrbutonJack's distribution is n is expected to be approximately normal. OB. Jack's distribution is expected to be Bewed lot, but more than the original distribution, Diane's distribution is expected to be approximately normal. OC. Diane's distribution is expected to be skewed right, but got as much as the original distribution. Jack's distribution is expected to be approximately normal OD Diane's distribution and Jack's distribution are expected to be approximately normal. However, Diane's will have a greater standard deviation What do you expect the mean of Diane's distribution to be? What do you expect the mean of Jack's distribution to be? Dane's distribution is expected to have a mean of Jack's distribution is expected to have a mean of (c) What do you expect the standard deviation of Diane's distribution to be? What do you expect the standard deviation of Jack's distrbution to be? Dane's distribution is expected to have a standard deviation of Jack's distribution is expected to have a standard deviation of (Round to two decimal places as needed)

Answer 1

solution- a) Loption c is but, C: Diane's nol as much right answer. distribution is expected to be right, as the original distribution. Jacks distribution is expected to be approximately noomal. b) Diane's distribution is expected a mean Or 141=60) Jack's distribution is expected to have mean of 160 to have a d Diane's distribution is expected to have a sd of 5 10 il Tour 10 JA Jacks is distribution expected 10 standard have deviation to 11-69035 of 35
