One class of N = 16 students who listens to calming music each day while working on arithmetic problems is chosen as the experimental group (group 1). Another class of N = 16 students serves as a control group with no music (group 2). Accuracy scores are measured for each child, and the average for students in the music condition is X = 86.75 with SS - 1250. For the no-music condition, the average is X = 78.8, with SS = 1180. B) Compute Cohen's d to estimate the size of the described effect (using the small, medium or large designation used in class) As d = , there was a effect of background noise on accuracy scores.tarleton.instructure.com *Course Hero Course Hero Course Hero *Course Hero [ Select ] Question 39 2 pts Question 6C- Hypothesis Decision Reminder: group 1= music group, and group 2= no music group For these data, Ho: / [ Select ] $ 12 and H1 : / [ Select ] As p [Select ] # 0.05, our data are [ Select ] under the null hypothesis.

C) Perform a hypothesis test to decide whether the population accuracy is significantly increased for students who listen to calming music (group 1) during study compared to those who do not listen to music (group 2). t = NOTE: Record the p-value exactly as it is in the PsyStat calculator. Record the t-statistic to two numbers after the decimal place
