Question:
According to Gartner Inc., the largest share of the worldwide PC market is held by HP Inc. with 19.8%. Suppose that a market analyst believes that HP Inc. holds a higher share of the market in Ontario. To verify this theory, he randomly selects 428 people who purchased a personal computer in the last month in Ontario. Ninety of these purchases were HP Inc. computers. Using a 1% level of significance, test the market analyst’s theory. If the market share is really 0.22 in Ontario, what is the probability of making a Type II error?
