Suppose jack and diane are each attempting to use a simulation to describe the sampling distribution from a population that is skewed left with mean 50 and standard deviation 10. jack obtains 1000 random samples of size n=4 from the population, finds 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=35 from the population.
1)describe the shape you expect for jacks distribution of sample means. describe the shape you expect for diane's distribution of sample means. choose the correct answer below.
a. diane's distribution is expected to be skewed right, but more than the original distribution. jack's distribution is expected to be approximately normal.
b. jack's distribution is expected to be skewed lleft, but not as much as the original distribution. diane's distribution is expected to be approximately normal.
c. jack 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.
d. jack's distribution and diane's distribution are expected to be approximately normal. however, jack's will have a greater standard deviation.
