on a 95-degree day with 80% humidity, the amount of time it takes an air-conditioning unit to cool a 2000-square-foot home 1 degree follows a normal distribution with mean time of 24 minutes and standard deviation of 1 minute. what is the probability it takes an air-conditioning unit longer than 25 minutes to cool the house 1 degree? (use the empirical rule.)
