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.
(a) Find the sample mean reading x and the sample
standard deviation s. (Round your answers to four
decimal places.)
(b) Find a 99.2% confidence interval for the population
mean of total calcium in this patient's blood. (Round your answer
to two decimal place.)
(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.
Yes. This confidence interval suggests that the patient no
longer has a calcium deficiency.
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.
