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 6mg/dl. Recently the patients total calcicum test gave the following readings in (mg/dl). Assume that the population of x values an approximately normal distribution.

9.9   9.4   10.5   8.5   9.4   9.8   10.0   9.9   11.2   12.1

xbar= 10.07

s=      1.00              I got this first part But cannot figue next part out.

Find a 99% Confidence Interval for the population mean of total calcium in this patients blood. (Round to 2 Decimal Places.)
