There that the mean calcium intake for all women in the desired age group is less than 1200 mg. convincing evidence BFW Publishers The recommended daily allowance (RDA) of calcium for women between the ages of 18 and 24 years is 1200 milligrams (mg). Researchers who were involved in a large scale study of women's bone health suspected that their participants had significantly lower calcium intakes than the RDA. To test this suspicion, the researchers measured the daily calcium intake of a random sample of 36 women from the study who fell in the desired age range. The sample mean was 856.2 mg and the standard deviation was 306.7 mg. Do these data give convincing evidence at the a = 0.01 significance level that the researchers' suspicion is correct?
