Sampling Distribution (Topic-2) T You're told that among all 18 sections of BUQU-1230 the average score on the first- midterm is 66 and the standard deviation is 15. Answer the following questions: 1.- If you took 400 samples, with 20 BUQU-1230 students in each sample, and found Che average of each 20-student sample what would the standard deviation of this sampling distribution be called? Calculate the value for the standard deviation of the sampling distribution. (2 points) O 2. + Referring to the 400 samples that you've taken (with 20 students in each sample), between what two values would you expect to find the middle 50%-of-the- sampled averages? (3 points) 3. Now let's say you took 400 samples, with 50 BUQU 1230 students in-each- sample, and found the average of each 50-student sample-what-would-the- standard deviation of the sampling distribution be? Between what two-values- would you expect to find the middle 50% of the sampled averages? (3-points) 1 4.- Explain the difference between your answers to 2 & 3. (2 points)
