You are given the null and alternative hypotheses and the sample information shown below. Complete parts a and b below. Sample 1 n1 = 120 S, = 34 X = 130 Sample 2 n2 = 135 HA: H1- H2#0 S2 = 36 X2 = 150 a. Develop the appropriate decision rule, assuming a significance level of 0.01 is to be used. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) O A. Reject Họ if t O B. Reject Họ if t> O C. Reject H, if t< b. Test the null hypothesis and indicate whether the sample information leads you to reject or fail to reject the null hypothesis. Use the test statistic approach. Calculate the value of the test statistic. t= (Round to two decimal places as needed.) Since the test statistic V in the rejection region, the null hypothesis. There is V evidence at a = 0.01 to conclude that the two population means are different.

Below is the question I am having a problem with as well as the portion of the answer I have come up with. I do not know if I am right or not, but I need an explanation to understand this, please. What information does the F ratio on the SPSS output for an independent sample T test provide? That is, what assumption does it test. A researcher might use the independent sample t test when he assumes that there will be equal mean populations between to variances. To calculate the independent sample t test, one would use this formula: t = m1-m2 SEm1-m2
