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. -------------------------------- QUESTION: Use a significance level of ΅ = 0.05 to test the claim that µ = 32.6. The sample data consist of...
