Presented below is a histogram of Beck Depression Inventory (BDI) scores ranging from 0 to 43. Looking at this histogram, what might make these data inappropriate to analyze using a t-test?  

Which diagnostic test is both therapeutic and diagnostic for suspected intussusception in a 9-month-old child presenting with intermittent crying and “currant jelly” stools?

  Fix the mistakes and report the findings correctly using the template from a prior question.  

  Construct a 95% CI estimating the size of the mean difference between the binge-watchers vs. daily-watchers.   95% CI [ [color1], [color2] ] (round up to two decimals).

Compute Cohen’s d to measure the size of the effect in the study in Q22. d = [color1] (round up to two decimals).

  Identify a critical t value for this study.   t =

Use a two-tailed test with α = .05 to examine the impact of binge-watching on the enjoyment of a show.    

  Please explain your choice in a prior question. Why is the test you selected most appropriate?  

  Compute the pooled variance, the estimated standard error of the mean difference, and the t statistic.   s2p = [color1] (round up to two decimals). s(M1 – M2) = [color2] (round up to two decimals). t = [color3] (round up to two decimals).

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.
