Assume that you have a sample of n, =9, with the sample mean X, =41, and a sample standard deviation of S, =4, and you have an independent sample of ny = 13 from another population with a sample mean of X, = 37 and the sample standard deviation Sz = 7. Complete parts (a) through (d). Click here for page 1 of critical values of t. Click here for page 2 of critical values of t [STAT = 1.5417 (Type an integer or a decimal rounded to four decimal places as needed.) b. In finding the critical value /2, how many degrees of freedom are there? 20 degrees of freedom c. Using a significance level of a = 0.1, what is the critical value for a one tail test of the hypothesis Ho: My 2 pz against the alternative Hy : , > p2? The critical value is 1 3253 (Type an integer or a decimal rounded to four decimal places as needed ) d. What is your statistical decision? O A. Do not reject Ho because the computed IsTAT test statistic is greater than the upper-tail critical value O B. Reject Ho because the computed tSTAT test statistic is less than the upper-tail critical value O C. Reject He because the computed teray test statistic is greater than the upper-tail critical value. O D. Do not reject Ho because the computed toTAT test statistic is less than the upper-tail critical value
