A random sample of 135 people yielded the following contingency table describing the relationship between migraine headaches and caffeine consumption (low, medium, high). Caffeine Consumption Low Med. High Migraine 5 8 15 No Migraine 35 42 30 Suppose we wish to test H0 : caffeine and migraines are independent versus Ha : caffeine and migraines are not independent at the α = 0.05 significance level. What is the value of the test statistic and p−value? TS = 5.37, p-value in (0.01, 0.02) TS = 5.37, p-value in (0.001, 0.0025) TS = 6.68, p-value in (0.05, 0.10) TS = 6.68, p-value in (0.025, 0.05) TS = 6.68, p-value in (0.01, 0.02) TS = 5.37, p-value in (0.02, 0.025)
