Question

Overproduction of uric acid in the body can be an indication of
cell breakdown. This may be an advance indication of illness such
as gout, leukemia, or lymphoma.† Over a period of months, an adult
male patient has taken thirteen blood tests for uric acid. The mean
concentration was *x* = 5.35 mg/dl. The distribution of uric
acid in healthy adult males can be assumed to be normal, with
*σ* = 1.81 mg/dl.

Find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. What is the margin of error? (Round your answers to two decimal places.)

lower limit | |

upper limit | |

margin of erro |

Answer #1

Solution :

Given that,

Sample size = n = 13

Z/2 = 1.96

Margin of error = E = Z/2* ( /n)

= 1.96 * (1.81 / 13)

Margin of error = E = 0.98

At 95% confidence interval estimate of the population mean is,

- E < < + E

5.35 - 0.98 < < 5.35 + 0.98

4.37 < < 6.33

lower limit: **4.37**

upper limit: **6.33**
