Over the past several months, an adult patient has been treated for tetany (sever 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. 9.1 8.6 10.9 8.7 9.4 9.8 10.0 9.9 11.2 12.1 x = mg/dl s = mg/dl (b) 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 (c) based on your results in part (b). do you think this patient still has a calcium deficienty? Explain.

x = mg/dl
s = mg/dl
(b) 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
(c) based on your results in part (b). do you think this patient still has a calcium deficienty? Explain.
