Verify that if the expected cell frequencies are calculated in accordance with the rule on page 372, their sum for any row or column equals the sum of the corresponding observed frequencies.
Answer to relevant QuestionsShow that the rule on page 372 for calculating the expected cell frequencies applies also when we test the null hypothesis that we are sampling r populations with identical multinomial distributions. In the test of a certain hypothesis, the P-value corresponding to the test statistic is 0.0316. Can the null hypothesis be rejected at the (a) 0.01 level of significance; (b) 0.05 level of significance; (c) 0.10 level of ...In 12 test runs over a marked course, a newly designed motorboat averaged 33.6 seconds with a standard deviation of 2.3 seconds.
