A paint manufacturer advertises that one gallon of its paint will cover sq ft of interior wall. Some local painters suspect the average coverage is considerable less and decide to conduct an experiment to find out. If µ represents the true average number of square feet covered by the paint, which of the following are the correct null and alternative hypothesis to be tested? A) H0: µ =400, Ha: µ > 400 B) H0: µ >400, Ha: µ > 400 C) H0: µ =400, Ha: µ ≠ 400 D) H0: µ ≠400, Ha: µ < 400 E) H0: µ =400, Ha: µ < 400
