A)Which of the following is true for the degrees of freedom? A. It represents the number of scores that are not free to vary B. It determines the critical value that we use in deciding whether or not to retain the null hypothesis C. It is important for both the z-test and the t-test D. It represents the degree to which you must run a t-test rather than a z-test b) If you randomly sample a group of people from a population and ask them to complete a memory test, the average memory score from your sample: A. may be different from the true population mean due to sampling error B. will be identical to the mean score of another sample drawn from the same population C. can be calculated by dividing the mean of the population by the number of people in your sample D. will be identical to the true population mean
