The SSRUR = 161.9, SSRR = 260.6, number of restrictions = 2, n = 89, and there are 8 right hand side variables. Calculate the F
statistic.
How does alpha levels and signifigance allow researchers to generalize the larger population from their test samples?
Define the Independent t Test for Two Samples and explain what why the word "independence" is used. In addition, come up with two hypothetical examples demonstrating this strategy or come up with "real-world" application using your professional life (i.e. how could you apply this in your work).

- Fifty boys and Fifty girls face off in a game of darts. The dependent variable is the number of bulls-eye scored and the distributions were normal. The boys averaged 5 bulls-eye/game (SD = 1.5). The girls scored an average of 6 bulls-eye/game (SD = 2). What is the observed value of the test statistic? What is the critical value for the boys v. girls darts game for a two-sided research hypothesis?arrow_forwardA researcher wanted to examine whether type of dog food (freeze dried meat vs generic brand kibble) would affect dogs' attention span. The researcher hypothesized that dogs who ate freeze dried meat would not have the same attention span as those who ate generic kibble. The researcher used a single sample of 13 dogs, that took part in both treatment conditions. The mean was 7.0 and the SS for the difference in attention spans was 144. Alpha was set at the 0.05 level. Calculate the appropriate t to the nearest thousandths and include the +/- value in front of the t. For example, -5.369. What is the corresponding critical t? What decision can you make about the null hypothesis? Was there a treatment effect?arrow_forwardA researcher wanted to examine whether type of dog food (freeze dried meat vs generic brand kibble) would affect dogs' attention span.

- A group of health conscious researchers were interested in ways to lower blood pressure. The study consisted of 90 participants. 30 participants were randomly assigned to eat a heart healthy diet, 30 were randomly assigned to a heart healthy exercise routine, and 30 were randomly assigned to do nothing and serve as a control. After a month of their assigned intervention, participants' blood pressure was measured. Which statistical test should be used to compare the 3 intervention types on post-treatment blood pressure? df between= ? df within= ? df total= ?arrow_forwardData is collected to compare two different types of batteries. We measure the time to failure of 10 batteries of each type. Battery A: mean= 8.65 Battery B: mean=11.23 Assume equal variances.
