To test H0: σ=2.2 versus H1: σ>2.2, a random sample of size n=24 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to be s=2.9, compute the test statistic. (b) If the researcher decides to test this hypothesis at the α=0.05 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis?
