Gravetter/Wallnau/Forzano, Essentials- Chapter 8-End-of-chapter question 15 AaAa A high school teacher has designed a new course intended to help students prepare for the mathematics section of the SAT. A sample of n - 20 students is recruited to take the course and, at the end of the year, each student takes the SAT. The average score for this sample is M- 562. For the general population, scores on the SAT ane standardized to form a normal distribution with . 500 and= 100. Standard Normal Distribution Mean-o.0 Standard Deviation-1.0 3.0 -2.0 0,0 0.00 1.0 2.0 3.0 Can the teacher condlude that students Use aone-taled test with -.01. who take the course score significantly higher than the general population? The null hypothesis is Ho:500 The standard error is 22.40 and2.77 ,whichis beyond the critical boundary of Reject the null hypothesis, and condude that students who take the course higher than the general population. Compute Cohen's d for this study. (Round your answer to three decimal places.) Cohen's d = Complete the following sentence demonstrating how the outcome of the hypothesis test and the measure of effect would aoear in a research reoort. O Type here to searchExplanation / Answer
standard error =100/sqrt(20) = 22.36
z = (M - mu)/se = (562 - 500)/22.36
= 2.7727
critical value = 2.327
reject as TS> critical
cohen's d = 62/100 = 0.62
which is medium effect size
now i don't know what are options given in the blanks
but the overall effect is significant
