To test upper h 0 : sigma equals 60 versus upper h 1 : sigma less than 60, a random sample of size n equals 25 is obtained from a population that is known to be normally distributed. (a) if the sample standard deviation is determined to be s equals 51.6, compute the test statistic. (b) if the researcher decides to test this hypothesis at the alpha equals 0.01 level of significance, use technology to determine the p-value. (c) will the researcher reject the null hypothesis?
