Question

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 4.86 grains and a sample standard deviation of 0.33 grain. Does this information provide strong evidence for concluding that the company is not filling its bottles as advertised? Test the appropriate hypotheses using $\alpha = 0.01$ by first computing the P-value and then comparing it to the specified significance level. State the appropriate hypotheses. $\circ$ $H_0: \mu = 5$ $H_a: \mu \ne 5$ $\circ$ $H_0: \mu = 5$ $H_a: \mu < 5$ $\circ$ $H_0: \mu \ne 5$ $H_a: \mu = 5$ $\circ$ $H_0: \mu = 5$ $H_a: \mu > 5$ Calculate the test statistic value and determine the P-value. (Round your test statistic to two decimal places. Round your P-value to three decimal places.) test statistic = (Round your answer to two decimal places.) P-value = (Round your answer to three decimal places.) State the conclusion in the problem context. $\circ$ Do not reject the null hypothesis. There is sufficient evidence to conclude that the company is not filling its bottles as advertised. $\circ$ Reject the null hypothesis. There is not sufficient evidence to conclude that the company is not filling its bottles as advertised. $\circ$ Do not reject the null hypothesis. There is not sufficient evidence to conclude that the company is not filling its bottles as advertised. $\circ$ Reject the null hypothesis.
