Is the t -test significant at a = 0.05? Specify how you arrived at your answer. The t-test is significant at the alpha 0.05, with a t-value of 4.217 and 18 degrees of freedom, a value chart with show that itis significant to the p = 0.001 6. If using SPSS, what is the exact likelihood of obtaining a t -test value at least as extreme or as close to the one that was actually observed, assuming that the null hypothesis is true? The probability of making a type 1 error would be the p- value achieved. This was 0.001, meaning there is a 0.1% chance that the null hypothesis is true. 7. Which group earned the most money post-treatment? The treatment group because they worked more hours. Veterans with disabilities (n = 10) who participated in a work assistance program earned significantly more money (M =$232.70, SD = $65.32) than those veterans (n = 10) with disability who did not receive work assistance (M = $128.40, SD = $43.02, t (18) = 4.217, p = 0.001). 8. Write your interpretation of the results as you would in an APA-formatted journal. Per the data provided by Ottomanelli and colleagues,” The null hypothesis is: “There is no difference between the treatment and control groups in post-treatment weekly wages earned among veterans with spinal cord injuries.” (Grove & Cipher, 2017, p. 360.)

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
