STATISTICS UNIT 7 EXAMPLES GRADED<>Which graph below corresponds to the following hypothesis test? H0:μ≥5.9, Ha:μ<5.9 The alternative hypothesis, Ha, tells us which area of the graph we are interested in. Because the alternative hypothesis is μ<5.9, we are interested in the region less than (to the left of) 5.9, so the correct graph is the first answer choice.
