A car manufacturer produced 5{,}0005,0005, comma, 000 cars for a limited edition model. Dealers sold all of these cars at mean price of \$36{,}000$36,000dollar sign, 36, comma, 000 with a standard deviation of \$3{,}000$3,000dollar sign, 3, comma, 000. Suppose we were to take random samples of 999 of these cars and calculate the sample mean price \bar x x ˉ x, with, \bar, on top for each sample. Calculate the mean and standard deviation of the sampling distribution of \bar x x ˉ x, with, \bar, on top. \mu_{\bar x}=
