Question
Over the past several months, an adult patient has been treated for tetany (svere 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. X = 9.8 S = 8.9 10.4 9.2 9.2 9.9 10.7 10.2 11.6 11.5 (a) Find the sample mean reading x and the sample standard deviation s.
