To test Ho: o= 2.1 versus H, :0> 2.1, a random sample of size n = 25 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to bes= 2.3, compute the test statistic. (b) If the researcher decides to test this hypothesis at the a = 0.10 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis?

Question
To test Ho: o = 2.1 versus H,:0> 2.1, a random sample of size n = 25 is obtained from a population that is known to be normally distributed. (a) If the sample standard deviation is determined to bes = 2.3, compute the test statistic. (b) If the researcher decides to test this hypothesis at the a = 0.10 level of significance, use technology to determine the P-value. (c) Will the researcher reject the null hypothesis? (a) The test statistic is x = 28.79. (Round to two decimal places as needed.) (b) The P-value is 0.228 . (Round to three decimal places as needed.) (c) Since the P-value is than the level of significance, the researcher V reject the null hypothesis Ho:o = 2.1.
