widely known that STM capacity 7 items (m=7)on average with a standard deviation of 2 items (s=2).
You randomly sampled n=8 participants and have then drink a large quantity of coffee. Fifteen minutes
later you administer a STM test to each participant and measure the number of items remembered.
The data are shown below. Use these data to answer the following questions. Excel should be used to
obtain the sample mean, standard deviation and standard error.
Perform a 2-tailed z-test with a=0.05 to determine if caffeine influences memory.
