A nutritionist claimed that the mean daily calcium intake for California women was 1000 milligrams. A random sample of 81 California women showed a sample mean= 960 milligrams with sample standard deviation s = 90 milligrams. Can you prove at 95% confidence that the nutritionist’s claim is not true? Before doing the problem, you must show that the problem meets the requirements for performing the test. To get full credit, you must state your null and alternate hypothesis, show how you calculated your test statistic, show your critical region, and state your conclusion: could the nutritionist’s claim be true? YES or NO
