The population mean zinc mass for a certain battery brand is believed to be 3.0 g. However, a recent random sample of 61 batteries had a mean mass of 3.08 g with sample standard deviation .152 g. Does this data provide compelling evidence that the population mean zinc mass exceeds 3.0 g? (a) Define the appropriate null and alternative hypotheses. (b) Using a significance level of .01, does this data provide compelling evidence that the population mean zinc mass exceeds 3.0 g?

Question
**Problem Statement:**

The population mean zinc mass for a certain battery brand is believed to be 3.0 g. However, a recent random sample of 61 batteries had a mean mass of 3.08 g with a sample standard deviation of 0.152 g. Does this data provide compelling evidence that the population mean zinc mass exceeds 3.0 g?

(a) Define the appropriate null and alternative hypotheses.

(b) Using a significance level of 0.01, does this data provide compelling evidence that the population mean zinc mass exceeds 3.0 g?

**Graph/Diagram Explanation:**

There are no graphs or diagrams in this problem. The problem is entirely text-based and requires statistical hypothesis testing.
