A start-up company is about to market a new computer printer. It decides to gamble by running commercials during a championship game. The company hopes that name recognition will be worth the high cost of the ads. The goal of the company is that over 38% of the public recognize its brand name and associate it with computer equipment. The day after the game, a pollster contacts 406 randomly chosen adults and finds that 172 of them know that this company manufactures printers.

Thus, there is insufficient evidence that more than 38% of the public recognizes the product. OB. No, because the null hypothesis is rejected. Thus, there is insufficient evidence that more than 38% of the public recognizes the product. OC. Yes, because the null hypothesis is not rejected. Thus, there is sufficient evidence that more than 38% of the public recognizes the product. O D. Yes, because the null hypothesis is rejected. Thus, there is sufficient evidence that more than 38% of the public recognizes the product.
