The marketing division of the food website unleashes an aggressive campaign designed to get Americans to consume even more popcom Complete parts (a) through (c) below. (a) Determine the null and alternative hypotheses that would be used test the effectiveness of the marketing campaign. Họ: H,: (Type integers or decimals. Do not round.) (b) A sample of 897 Americans provides enough evidence to conclude that marketing campaign was effective. Provide a statement that should be put out by the marketing department. O A. There is sufficient evidence to conclude that the mean consumption of popcorn has stayed the same. O B. There is sufficient evidence to conclude that the mean consumption of popcorn has risen. OC.

There is not sufficient evidence to conclude that the mean consumption of popcorn has risen. c) Suppose, in fact, the mean annual consumption of popcom after the marketing campaign is 58 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, what is the probability of committing this error?

The marketing department committed a Type Il 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. O B. 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. O C. 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 O D. The marketing department committed a Type I error because the marketing department rejected the null hypothesis when it was true. The probability of making a Type I error is
