According to a study done this year by Move.org, the cost of living in San Diego was right-skewed with a mean of $2,665 and a standard deviation of $1,344.   a) Suppose we sampled 20 San Diegans. Can you use the sampling distribution for means? What about 40 San Diegans? Explain. Fill in the blanks to find the sampling distribution of the mean cost of living for a sample of 40 San Diegans. Round to three decimal places, if possible. ?̅~_______(         ,           )   c) Find the probability that a sample of 40 San Diegans will have a mean cost of living greater than $3,000. Round to three decimal places.
