Show 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.
Answer to relevant QuestionsShow that the following computing formula for x2 is equivalent to the formula on page 372: With reference to Example 13.1, verify that the P-value corresponding to the observed value of the test statistic is 0.0046. Example 13.1 Suppose that it is known from experience that the standard deviation of the weight of ...With reference to the preceding exercise, find the required size of the sample when σ = 9, µ0 = 15, µ1 = 20, α = 0.05, and β = 0.01. Sample surveys conducted in a large county in a certain year and again 20 years later showed that originally the average height of 400 ten-year-old boys was 53.8 inches with a standard deviation of 2.4 inches, whereas 20 ...In a random sample, the weights of 24 Black Angus steers of a certain age have a standard deviation of 238 pounds. Assuming that the weights constitute a random sample from a normal population, test the null hypothesis σ = ...
