Which of the following z-score values represents the location closest to the mean?

7 =40.50 Z =+1.00 O Z=-1.00 2=-2.00O Above the mean by 2 points O Above the mean by a distance equal to 2 standards deviations Below the mean by 2 points O Below the mean by a distance equal to 2 standard deviations\fO It also increases O It decreases It stays constant O The standard error does not change in a predictable manner when sample size increases18 O 80/3 80increases the probability of type I error increases the size of the critical region increases the probability that the sample will fall into the critical region decreases the probability of type I errorTrue False20 16 15
