When 32 people 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 (mmol/l) and albumin (g/l) for each individual at the time of hospital admission are shown in the vitamin D table below

1. Create a SAS data set from table of vitaminD below. Use PROC MEANS to calculate the sample mean and sample standard deviation for blood levels of calcium and albumin. Turn in your SAS program and the PROC MEANS results.
2. Construct a 99% confidence interval for the true mean calcium level of individuals who experience vitamin D intoxication.
3. Construct a 99% confidence interval for the true mean albumin level of this group.
4. For healthy individuals, the normal range of calcium value is 2.12 to 2.74 mmol/l 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?
