The amounts of electricity bills for all households in a city have a skewed probability distribution with a mean of $140 and a standard deviation of $30. Find the probability that the mean amount of electric bills for a random sample of 75 households selected from this city will be more than the population mean by at least $4. Round your answer to four decimal places. P (i greater than u by at least $4) the tolerance is +/-2%
