To test Ho: 6 = 2.4 versus H1: 6> 2.4, a random sample of size n = 17 is obtained from a population that is known to be normally distributed. Complete parts (a) through (a) If the sample standard deviation is determined to be s = 2.2, compute the test statistic. x3 = (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. Xo.05 = (Round to three decimal places as needed.) (c) Draw a chi-square distribution and depict the critical region. O O O O 7.962 26.296 13.44 26.3 13.44 26.3 7.962 26.296 (d) Will the researcher reject the null hypothesis? O Reject Ho because Xo Xo.05 . O Do not reject Ho because xo X0.05 . Next
