Fifteen percent of new residential central air conditioning units installed by a supplier need additional adjustments requiring a service call. Assume that a recent sample of seven such units constitutes a binomial process. Interest centers on X, the number of units among these seven that need additional adjustments. The mean and variance of X are, respectively O 1.05, .945 O.15, 945 0 15, .85 1.05, .893 None of the other answers are correct O 15, 893
