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: 01:26:37
