Write a two to three (2-3) page report in which you:

  • Calculate the mean, median, and standard deviation of the number of tablets.
  • Construct a 95% Confidence Interval for the tablet count.
  • Conduct a hypothesis test to verify if the claim that the bottles contain less than 500 tablets is supported. Clearly state the logic of your test, the calculations, and the conclusion of your test.
  • Provide the following discussion based on the conclusion of your test:

a. If you conclude that the bottles have less than 500 tablets, speculate on three (3) possible causes. Next, suggest the strategies to improve the performance in the future.

Or

b. If you conclude that the claim of the bottle complaints is not supported or justified, provide a detailed explanation to your boss about the situation. Include your speculation on the reason(s) behind the claim recommend one (1) strategy geared toward mitigating this issue in the future.
