# Which shows 23^2017^2 being evaluated using the difference of perfect squares method?

a.23^3017^2=(529+289)(5290289)=196, 320

b.23^2017^2=5290289=240

c.23^2017^2=(23+17)(23017)=(40)(6)= 240

d.23^2017^2=(23017)^2=(6)^2=36

Assume that data set a depicts the scores of 10 subjects who received either treatment 1 or treatment 2. calculate a t-test for independent means to determine whether the means are significantly different from each other. use a two-tailed alpha of .05 to make your decision. in your complete answer, remember to include your t-statistic, critical value, and your decision about whether to reject the null hypothesis. for this question, you should assume that different participants received the two different treatments. (15 points) 2. now assume that data set a depicts the scores of five subjects who received both treatment 1 and treatment 2. calculate a t-test for dependent means to determine whether the means for the two treatments were significantly different. the correlation between the two treatments is +1.00. use a two- tailed alpha of.05 to make your decision. in your complete answer, remember to include your t-statistic, critical value, and your decision about whether to reject the null hypothesis. for this question, you should assume that the same participants received each of the two treatments. (15 points) assume that 18 subjects received one of three treatments and produced the data reported in data set b. 3. conduct a one-way anova to see if the means of the three treatments are different on a statistically significant level, using a two-tailed alpha of .05. complete an anova table reporting the relevant ss df, ms, and f. also remember to include your critical value and whether you would reject your null hypothesis. (20 points) data set a treatment 1 treatment 2 45 50 60 70 55 80 60 65 90 100 data set b treatment treatment 2 treatment 3 50 60 70 55 60 65 70 80 90 45 65 55 55 70 85 45 40 35
