11. [-/9.09 Points] DETAILS BBBASICSTATSACC 8.2.017.M Over the past several months, an adult patient has been treated for telany ( severe muscle spasms). This condition is associated with an average total calcium level below 6 mg/di. Recently, the patient's total calcium tests gave the following readings (in=mq/dl). Assume that the population of x values has an approximately normal distribution. 9.1 9.2 10.1 9.5 9.4 9.8 10.0 9.9 11.2 12.1 (a) Use a calculator with mean and sample standard deviation keys to find the sample mean reading x and the sample standard deviation s. (in mg/di; round your answers to two decimal places.) X ma/dl mg/al (h) Find # 99.9% confidence Interval for the population mean of total calcium in this patient's blood. (in mg/di; 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 deficiency? Explain. Yes. This confidence interval suggests that the patient may still have a calcium deficiency. O Yes. This confidence interval suggests that the patient no longer has a calcium deficiency. O No. This confidence interval suggests that the patient may still have a calcium deficiency. ) No. This confidence interval suggests that the patient no longer has a calcium deficiency. 10:53 AM
