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.
