Dr. Mutombo would like to assess the impact of using an online statistics service to help students study for the PSY 215 departmental final exam. A sample of 12 students is obtained. Half (n 6) are given access to the new stats online service while the other half (n = 6) serves as a control group. Each group of students is eventually tested on an exam out of a 100. Below is the data obtained: Answer the following questions. Show your work for full credit and round to the third decimal whenever necessary. Control Group Experimental Group M1=63 M2=88 SS1=1250 SS2=1750 a. State your hypotheses b. Does the data indicate a aignificant difference between the treatments for a two-tailed test at the .05 level of significance? Please specify (1) the t statistic, (2) specify the boundaries of the critical region, (3) state your decision. Show your computations for full credit c. Compute r2 d. Write up your results in a sentence as you would for a research paper; use APA format.

Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
