Help please :,)

Assume that you have a sample of n, = 7, with the sample mean X, =45, and a sample standard deviation of S, = 6, and you have an independent sample of n2 = 15 from another population with a sample mean of X2 = 33 and the sample standard deviation S2 =5. 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. a. What is the value of the pooled-variance tSTAT test statistic for testing Ho: H1 = H2? ISTAT = . (Type an integer or a decimal rounded to four decimal places as needed.) b. In finding the critical value to / 2, how many degrees of freedom are there? degrees of freedom c. Using a significance level of a = 0.05, what is the critical value for a one-tail test of the hypothesis Ho: H1 S H2 against the alternative H1 : Hy > #2? The critical value is .. (Type an integer or a decimal rounded to four decimal places as needed.) d. What is your statistical decision? O A. Reject Ho because the computed tSTAT test statistic is less than the upper-tail critical value. O B. Do not reject Ho because the computed tSTAT test statistic is less than the upper-tail critical value. O C. Reject Ho because the computed tSTAT test statistic is greater than the upper-tail critical value. O D. Do not reject Ho because the computed tSTAT test statistic is greater than the upper-tail critical value
