Solved: An aspirin manufacturer fills bottles by weight
Chapter 8, Problem 8.53(choose chapter or problem)
An aspirin manufacturer fills bottles by weight rather than by count. Since each bottle should contain 100 tablets, the average weight per tablet should be 5 grains. Each of 100 tablets taken from a very large lot is weighed, resulting in a sample average weight per tablet of 4.87 grains and a sample standard deviation of .35 grain. Does this information provide strong evidence for concluding that the company is not filling its bottles as advertised? Test the appropriate hypotheses using .01 by first computing the P-value and then comparing it to the specified significance level.
