Can people really identify their favorite brand of cola? volunteers tasted coke, pepsi, diet coke, and diet pepsi, with the results shown below. at α = .05, is the correctness of the prediction different for regular cola and diet cola drinkers? for regular cola: 6- got it right, 18- got it wrong and 24-total. for diet cola: 10- got it right, 14- got it wrong and 24-total. row total: 16- got it right, 32- got it wrong and 48-total. (a) the hypothesis for the given issue is: h0: type of cola drinker and correct response are independent. (b) calculate the chi-square test statistic, degrees of freedom, and the p-value. (round your test statistic value to 2 decimal places and the p-value to 4 decimal (c) find the critical value of the chi-square for ? = 0.05. (round your answer to 3 decimal (d) we reject the null hypothesis and conclude dependence. (e) perform a two-tailed, two-sample z test for = . (round your z2 to 2 decimal places and p-value to 4 decimal (f) we get the same p-value result using a two-tailed test of two proportions as we do using the chi-square test statistic.
