**Question**

Over the past several months, an adult patient has been treated for tetany (severe muscle spasms). This condition is associated with an average total calcium level below 6 mg/dl. Recently, the patient's total calcium tests gave the following readings (in mg/dl). Assume that the population of *x* values has an approximately normal distribution.

9.7 |
8.8 |
10.7 |
8.9 |
9.4 |
9.8 |
10.0 |
9.9 |
11.2 |
12.1 |

Find a 99.9% confidence interval for the population mean of total calcium in this patient's blood. (in mg/dl; round your answer to two decimal places.)

lower limit mg/dl

upper limit mg/dl
