Calculate test statistic and find the p-value

Reference no: EM131071281

When operating normally, a manufacturing process produces tablets for which the mean weight of the active ingredients is 5 grams, and the standard deviation is 0.025 gram. For a random sample of 12 tablets the following weights of active ingredient (in grams) were found:

5.01 4.69 5.03 4.98 4.98 4.95

5.00 5.00 5.03 5.01 5.04 4.95

Without assuming that the population variance is known, test the null hypothesis that the population mean weight of active ingredient per tablet is 5 grams. Use a two-sided alternative and a 5% significance level. State any assumptions that you make.

I need to include the following in my answer:

1. The problem statement

2. Assumptions

3. The null and alternate hypothesis statements

4. The significance level

5. The test statistic

6. Decision Rules

7. Calculate Test Statistic and find the p-value

8. Interpret the results of the test.
