Assume that a simple random sample has been selected from a normally distributed population and test the given claim.
Use either the traditional method or P-value method as indicated. Identify the null and alternative hypotheses, test statistic, critical value(s) or P-value (or range of P-values) as appropriate, and state the final conclusion that addresses the original claim.
-Use a significance level of $\alpha = 0.01$ to test the claim that $\mu 2.85$. The sample data consist of 9 scores for which $\bar { x } = 3.19$ and $s = 0.55$. Use the traditional method of testing hypotheses.
