To test H0:=4.6 versus H1:4.6, a random sample of size n=13 is obtained from a population that is known to be normally distributed.

(a) If the sample standard deviation is determined to be s=6.7, compute the test statistic.

(b) If the researcher decides to test this hypothesis at the =0.10 level ofsignificance, use technology to determine theP-value.

(c) Will the researcher reject the nullhypothesis?

The test statistic is x₀²=

TheP-value is=

Since theP-value is greater, less

than the level ofsignificance, the researcher will not, will

reject the null hypothesis H0:=4.6.
