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 15 scores for which x = 42.5 and s = 5.9. Use the traditional method of testing hypotheses.
--------------------------------
ANSWER:

H0: µ = 32.6.
H1: µ J 32.6.
Test statistic: t = 6.50.
Critical values: t = ±2.145. Reject H0.
There is sufficient evidence to warrant rejection of the claim that the mean is 32.6.

Answer #1

Here 2 = 0.05 lo= 32.6, 7 = 42.5 and s=s.g Hence ho: 4 = 32.6 US HNE 32-6 Test statistics = t a. S = 42.5-32.6 - g.g 5.9 1.52
