The annual turnover rate of the 200-count bottle of aspirin, Ask an Expert

Statistics

Interpret the result and test whether to reject hypothesis for mean.

The annual turnover rate of the 200-count bottle of aspirin follows the normal distribution with a mean of 6.0 and a standard deviation of 0.50. (This indicates that the stock of asprin turns over on the pharmacy shelves an average of 6 times per year.) It is suspected that mean turnover has changed and is not 6.0. Employ the .05 significance level.

A random sample of 64 bottles of the 200-count size asprin showed a mean turnover rate of 5.84. Shall we reject the hypothesis that the population mean is 6.0? Interpret the result.
