Statistics

Q4. The following table contains observed frequencies for a sample of 240. Test for independence of the row and column variables using a = 0.05. Column Variable Row Variable A B C P 30 48 50 Q 42 40 30 (A). What is f23 (i.e., observed frequency) value? (3%) (B). What is e23 (i.e., expected frequency) value? (3%) (C). What is the test statistic value? (6 points) (D). Observing the x2 table, what is the possible range of values of the p-value? [Multiple choice question (single answer)] (6 points) (a) 0.025 0.05, we do not reject Ho. (c) Because p-value = 0.05, we reject Ho. (d) Because p-value > 0.05, we reject Ho. (e) Because p-value - test statistic, we reject Ho. (f) None of the above
