According to Gartner Inc., the largest share of the worldwide PC market is held by Hewlett- Packard with 19.8%. Suppose that a market researcher believes that Hewlett-Packard holds a higher share of the market in Ontario. To verify this theory, he randomly selects 429 people who purchased a personal computer in the last month in Ontario. Ninety of these purchases were Hewlett-Packard computers. Using a 1% level of significance, test the market researchers theory. If the market share is really 0.22 in Ontario, what is the probability of making a Type II error? (Round the values of z to 2 decimal places, e.g. 0.75. Round the intermediate values to 4 decimal places, e.g. 0.7589.Round your answer to 4 decimal places, e.g. 0.7589.).
