Lets say there is 36 people completed a experiment where ads are presented subliminally during a task.The people are then given a recognition test for images of the ads, where two images are presented and the people must choose which one of the two was presented earlier. Both men and women (18 of each gender) participate in the study and the researcher predicts that the recognition accuracy will differ across gender.

A. State the alternative and null hypotheses for this study.

B. The difference between the sample means in this study was 6%. The SS for the mean was 250 and the SS for the women was 150. Calculate the sample t score for this study (remember to start with the pooled variance before you calculate the estimated standard error).

C. What decision should the researcher make about the null hypothesis in this study? What can the researcher conclude about their prediction from this decision?

D. For the following set of data from two independent samples, conduct an independent samples t testusing SPSS to determine if the mean scores for each sample are significantly different
