Question 49

Question 50 1 pts A study is designed to test whether there is a difference in mean daily calcium intake in adults with normal bone density, adults with osteopenia (a low bone density which may lead to osteoporosis) and adults with osteoporosis. Adults 60 years of age with normal bone density, osteopenia and osteoporosis are selected at random from hospital records and invited to participate in the study. Each participant's daily calcium intake is measured based on reported food intake and supplements. The data are shown below. Normal Bone Density Osteopenia Osteoporosis 1250 1000 900 990 1090 700 980 700 1050 850 810 900 750 500 400 800 700 350 Is there a statistically significant difference in mean calcium intake in patients with normal bone density as compared to patients with osteopenia and osteoporosis? We will run the ANOVA using the five-step approach. Compute p-value (in 4 decimal places) and compare with a
