Extracted text: 10. When eight persons in Massachusetts experienced an unexplained episode of vitamin D intoxication that required hospitalization, it was suggested that these unusual occurrences might be the result of excessive supplementation of dairy milk. Blood levels of calcium and albumin for each individual at the time of hospital admission are shown below. Calcium (mmol/l) Albumin (g/l) 2.99 40 3.79 41 3.17 36 2.48 41 3.25 46 3.47 42 2.39 39 3.21 40 (a) Construct a one-sided 95% confidence interval-a lower bound-for the true mean calcium level of individuals who experience vitamin D intoxication. (b) Compute a 95% lower confidence bound for the true mean albumin level of this group. (c) For healthy individuals, the normal range of calcium values is 2.12 to 2.74 mmol/1 and the range of albumin levels is 32 to 55 g/l. Do you believe that patients suffering from vitamin D intoxication have normal blood levels of calcium and albumin?
