To test Hh: o=2.3 versus H:o> 2.3, a random sample of size n= 15 is obtained from a population that is known to be norrmally distributed. Cormplete parts (a) through (d). (a) If the sample standard deviation is determined to be s = 2.1, compute the test statistic. (Round to three decimal places as needed.) (b) If the researcher decides to test this hypothesis at the a= 0.05 level of significance, determine the critical value. (Round to three decimal places as needed.) (c) Draw a chi-square distribution and depict the critical region. 11.67 23.69 6.571 23.685 11.67 23.69 (d) Will the researcher reject the null hypothesis?
