- Determine whether the statement is true or false. If it is false, rewrite it as a true statement. As the size of a sample increases, the standard deviation of the distribution of sample means increases. Choose the correct choice below. C OA. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means decreases." OB. This statement is true. OC. This statement is false. A true statement is, "As the size of a sample decreases, the standard deviation of the distribution of sample means decreases." OD. This statement is false. A true statement is, "As the size of a sample increases, the standard deviation of the distribution of sample means does not change." Time Remaining: 01:26:37For an Economics test the mean score is 100 and the standard deviation is 10, and for an Accounting test the mean score is 50 and the standard deviation is 4. You are given the test scores of a student who took both tests. Determine on which test the student had a better score. Enter E if the student did better on the Economics test Enter A if the student did better on the Accounting test Enter S if the student did relatively the same on both tests. A student scores 125.6 on the Economics test and 60.2 on the Accounting test. The student did better/same on test.q6
