Explain your decision in the previous question. How did you determine whether the H0 can be rejected with different significance levels or not? Please make sure to include the value of a calculated t statistic and critical values for both tests. 

What is the sample variance and standard deviation for the sample in Q22? s2 = [color1] s = [color2] (round up to two decimals)

  Several mistakes were made when reporting the findings. What are they? Binge-watching appears to significantly diminish a TV show’s enjoyment, t(11) = – 2.93, p < .05, d = 1.86. On average, those who watched a show in a single binge session (M = 81.5, SD = 6.03) enjoyed it less than those who watched a show on a daily basis (M = 90, SD = 7.85).  

  How many degrees of freedom are there in this study?   df = [color1]

Using a one-tailed test to evaluate the effect of the new cold medication, what decision should be made?

Binge-watching is defined as watching multiple episodes of a TV show in a short time. It has been shown to have some negative psychological effects, including sleep disturbances, reduced productivity, social isolation, and eating disorders. In addition, there is evidence that binge-watching may impact the enjoyment of a show.  Specifically, Horvath et al. (2017) revealed that binge-watchers reported enjoying a TV show significantly less than people who watched the same show on a daily or weekly schedule. To examine this phenomenon, you randomly assigned participants to watch an entire TV series in the lab during either daily one-hour sessions or a single binge session. Participants were then asked to rate their enjoyment of the series on a scale of 0 – 100. Their ratings are presented below.
