An industry expert claimed that sporting goods stores average sales of $260 a square foot. A hypothesis test was requested to determine if the data supported the statement made by the expert using an a = 0.05 and a sample size of 41. Calculate the probability that the data will indicate that sporting goods stores do average sales of $260 per square foot when the true average is

$300 per square foot. Assume a population standard deviation of 100. The file called Apparel contains data for a random sample of several competitors’ sales per square foot. Use a = 0.05.
