Suppose we want to test the concentration (μg/mL) of a specific dose of penicillin in the blood at a certain period of time. We randomly select 35 volunteers who have received penicillin and find they have a mean of 7.0 µg/mL. Past studies indicate the standard deviation is 2.0 μg/mL. The researcher thinks the mean concentration level will be at most 8.0. Test at a significance level of 0.05. (Round to the nearest hundredth 0.00) a) What is the null and alternative hypothesis? Ho: Ha: b) What is the test statistic and calculate its value? c) Find the p-value or critical value depending on the test statistic used above. d) What is your decision and interpretation?
