Question
Vitamin D, whether ingested as a dietary supplement or produced naturally when sunlight falls upon the skin, is essential for strong, healthy bones. The bone disease rickets was largely
eliminated during the 1950s, but now there is concern that a generation of children more likely to watch TV or play computer games than spend time outdoors is at increased risk. A recent
study of 2900 children randomly selected found 23% of them deficient in vitamin D. Complete parts a through c below.
a) Construct a 98% confidence interval for the true proportion of children who are deficient in vitamin D. Select the correct choice below and fill in any answer boxes within your choice.
O A. (D
(Round to three decimal places as needed.)
O B. The conditions of a confidence interval are not satisfied.
b) Explain carefully what the interval means.
O A. We are 98% confident that the proportion of vitamin D deficiency in a randomly sampled child falls within the confidence interval bounds.
O B. We are 98% confident that the proportion of children deficient in vitamin D falls inside the confidence interval bounds.
O C. We are 98% confident that the proportion of people deficient in vitamin D falls inside the confidence interval bounds.
