Use the formula of Exercise 13.16 to recalculate x2 for Example 13.10.
Answer to relevant QuestionsIf the analysis of a contingency table shows that there is a relationship between the two variables under consideration, the strength of this relationship may be measured by means of the contingency coefficient Where x2 is ...With reference to Example 13.3, use suitable statistical software to find the P-value that corresponds to t = –0.49, where t is a value of a random variable having the t distribution with 4 degrees of freedom. Use this ...With reference to Exercise 13.30, use suitable statistical software to find the P-value that corresponds to the observed value of the test statistic. Use this P-value to rework the exercise. In exercise Five measurements of ...Suppose that independent random samples of size n from two normal populations with the known variances σ21 and σ22 are to be used to test the null hypothesis µ1 – µ2 = ∂t against the alternative hypothesis µ1 – ...With reference to Exercise 13.4, find the required size of the samples when σ1 = 9, σ2 = 13, ∂ = 80, ∂t = 86, α = 0.01, and β = 0.01.
