    5. Using z-scores with the distribution of sample means On each trial of a digit span memory task, the partiapant is asked to read aloud a string of random digits. The partidpant must then repeat the digits in the correct order. If the participant is successful, the length of the next string is increased by one. For instance, if the partidpant repeats four digits successfully, she will hear five random digits on the next trial. The partiipant's score is the...

    Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor would...
