city bills: According to a government energy agency, the mean monthly household electricity bill in the United States in as $109.72. Assume the amounts are normally distributed with standard deviation $24.00. Use the TI-84 Plus calculator to the following. at proportion of bills are greater than $131? at proportion of bills are between $87 and $140? at is the probability that a randomly selected household had a monthly bill less than $125? the answers to at least four decimal places. 1 of 3 proportion of bills that are greater than $131 is 2 of 3 proportion of bills that are between $87 and $140 is 3 of 3 X probability that a randomly selected household had a monthly bill less than $125 is X
