Question

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 Pvalue 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. 17)
Use a significance level of΅= 0.01 to test the claim that µ> 2.85. The sample data consist of
9 scores for which x = 3.1 and s = 0.6. Use the traditional method of testing hypotheses.
