Suppose diane and jack are each attempting to use a simulation to describe the sampling distribution from a population that is skewed right with mean 70 and standard deviation 15. diane obtains 1000 random samples of size nequals4 from the population, finds the mean of the means, and determines the standard deviation of the means. jack does the same simulation, but obtains 1000 random samples of size nequals40 from the population. (a) describe the shape you expect for jack’s distribution of sample means. describe the shape you expect for diane’s distribution of sample means.

(b) what do you expect the mean of jack’s distribution to be? what do you expect the mean of diane’s distribution to be?

(c) what do you expect the standard deviation of jack’s distribution to be? what do you expect the standard deviation of diane’s distribution to be?
