188 1888 website, the mean consumption of popcom annually by Americans is 59 quarts. The marketing division of the food website unleashes an aggressive campaign designed to get Americans to consume even more popcorn. C parts (a) through (c) below (a) Determine the null and alternative hypotheses that would be used to test the effectiveness of the marketing campaign. Ho H H₂ # H (Type integers or decimals. Do not round.) (b) A sample of 832 Americans provides enough evidence to conclude that marketing campaign was effective. Provide a statement that should be put out by the marketing department = 59 59 OA. There is sufficient evidence to conclude that the mean consumption of popcomn has risen OB. There is sufficient evidence to conclude that the mean consumption of popcorn has stayed the same. OC. There is not sufficient evidence to conclude that the mean consumption of popcorn has risen. OD. There is not sufficient evidence to conclude that the mean consumption of popcorn has stayed the same. (c) Suppose, in fact, the mean annual consumption of popcorn after the marketing campaign is 59 quarts. Has a Type I or Type Il error been made by the marketing department? If we tested this hypothesis at the a= 0.05 level of significance, w is the probability of committing this error? Select the correct choice below and fill in the answer box within your choice. (Type an integer or a decimal. Do not round.) OA. The marketing department committed a Type I error because the marketing department did not reject the alternative hypothesis when the null hypothesis was true. The probability of making a Type I error is OB. The marketing department committed a Type II error because the marketing department did not reject the alternative hypothesis when the null hypothesis was true. The probability of making a Type Il error is OC. The marketing department committed a Type Il error because the marketing department rejected the null hypothesis when it was true. The probability of making a Type Il error is
