State the null and research hypotheses. Choose the correct answer below.
O A. The null hypothesis is that the population is 5% category A, 14% category B, 35% category C, 31% category D, 14% category E, and 1% category F. The research
hypothesis is that the percent in each category of the population is different.
O B. The null hypothesis is that the percent in at least one category of the population is different. The research hypothesis is that the population is 5% category A, 14%
category B, 35% category C, 31% category D, 14% category E, and 1% category F.
O C. The null hypothesis is that the population is 5% category A, 14% category B, 35% category C, 31% category D, 14% category E, and 1% category F. The research
hypothesis is that the percent in at least one category of the population is different.
Determine the cutoff sample score at which the null hypothesis should be rejected.
The cutoff value is.
(Round to three decimal places as needed.)
Determine the chi-square statistic.
x = (Round to three decimal places as needed.)
Decide whether to reject the null hypothesis.
Ho. At the 0.01 significance level, there
V sufficient evidence to conclude that the category distribution of the two populations are different.
