A nutritionist wants to know if the mean daily calorie intake of men is less than that of women. She collects data from 6060 men (mean =2400=2400, population standard deviation =350=350) and 5555 women (mean =2550=2550, population standard deviation =330=330). At α=0.10 \alpha = 0.10 , what is the critical value and the rejection region for this hypothesis test?

Critical value =−1.282=-1.282Rejection region: z−1.282z

Critical value =1.645=1.645Rejection region: 1.645"\u003ez\u003e1.645z\u003e1.645
