At the 5% significance level, do we have good evidence that these cats are too small? State the hypotheses, find the test statistic and p-value and state the decision.
b. State the decision in the context of the problem.
c. Suppose some of the lengths of the cats were recorded incorrectly, and the true average of the hellbenders was 22 cm. Did you just find a Type I error, a Type II error or make the correct decision? Explain, using definitions
