The Z-score corresponding to the mean of Sample 103 is Use the Distributions tool that follows to determine the probability of obtaining a mean number of digits successfully repeated greater than the mean of Sample 103. The mean for Sample 103 is for Sample 103 is Using the distribution of sample means, calculate the 2-score corresponding to the mean of Sample 103. The standard deviation Use the DataView tool to find the mean and the standard deviation for Sample 103. The samples are numbered in the first column, and you can use the scroll bar on the right side to scroll to the sample you want.).

(Hint: Use the population mean and/or standard deviation just The expected value of the mean of the 64 randomly selected students, M, is given to calculate the expected value of M.) The standard error of M Is (Hint: Use the population mean and/or standard deviation just given to calculate the standard error.) The DataView tool that follows displays a data set consisting of 200 potential samples (each sample has 64 observations). The professor knows that the distribution of scores is normal, but she does not know that the true average number of digits successfully repeated on the digit span task among college students is 7.06 digits with a standard deviation of 1.610 digits. She measures the number of digits successfully repeated for 64 randomly selected students. A professor of cognitive psychology is interested in the number of digits successfully repeated on the digit span task among college students. The participant's score is the longest string of digits she can successfully repeat. For instance, if the participant repeats four digits successfully, she will hear five random digits on the next trial. If the participant is successful, the length of the next string is increased by one. The participant must then repeat the digits in the correct order.
On each trial of a digit span memory task, the participant is asked to read aloud a string of random digits.
