As humans we consume food. The body extracts good things such as proteins and vitamins and throws away waste. A typical waste product is a uric acid. High levels of uric acid can be an indication of conditions such as gout, kidney disease, and cancer. For females a high level of uric acid is 6 mg/dL or more and for males a high level of uric acid is 7 mg/dL or more. Suppose, over a period of months, an adult female has taken 8 blood test for uric acid. The results of the test are shown below. results 8.9 6.27 3.99 7.42 9.94 8.99 9.17 5.65 Find a 95% confidence interval for the population mean of uric acid in this adult female's blood. (Round your answers to two decimal places.) margin of error mg/dL lower limit mg/dL upper limit mg/dL Does this confidence interval suggest that this adult female has a high level of uric acid? Explain your answer

Find a 95% confidence interval for the population mean of uric acid in this adult female's blood. (Round your answers to two decimal places.)
margin of error mg/dL
lower limit mg/dL
upper limit mg/dL
