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.
