Use software to test the null hypothesis of whether there is a relationship between the two classifications, A and B, of the 3×3 contingency table shown below. Test using α=0.01. NOTE: You may do this by hand, but it will take a bit of time. B1 B2 B3 Total A1 40 68 55 163 A2 40 44 77 161 A3 64 71 63 198 Total 144 183 195 522 (a) χ2= (b) Find the degrees of freedom. (c) Find the critical value. χ2= (d) The final conclusion is A. We can reject the null hypothesis that A and B are not related and accept that there seems to be a relationship between A and B. B. There is not sufficient evidence to reject the null hypothesis that there is no relationship between A and B

    Let R be a binary relationship between the entity sets E1 and E2. Consider the following instances for E1, E2, and R: E1 = {a1, a2, a3, a4, a5, a6} E2 = {b1, b2, b3, b4, b5, b6, b7} R = {(a1, b1), (a2, b1), (a3, b2), (a4, b4), (a5, b6), (a6, b6)} Draw the E/R diagram for E1, E2 and R indicating the strongest constraints (most restrictive) in terms of key and participation constraints you can define such that...

    A recent study by the World Bank wished to determine whether there was a relationship between the abundance of natural resources in a country and its long term rate of economic growth. Their study used 40 (n) countries over a long period to 1995. Letting Y be the rate of growth measured as a percentage and X be a measure of natural resource abundance, the following relationship between the two variables was estimated. Standard errors of b0 and b1 are...

    You are testing the null hypothesis that there is no relationship between two variables, X and Y. From your sample of n = 22, you determine that SSR = 80 and SSE = 20. Construct the ANOVA table, test for model significance at a 0.05 level of significance and state your conclusion, and calculate the coefficient of determination and interpret its meaning.
