Does mental repetition help with memory? Researchers want to test the effect of repeating words so they have 9 individuals practice repeating a list of words 5 times before writing down how many words they can remember. Did this group of participants who used repetition have significantly better memory norm?
a) Yes, because the mean memory score is higher than the population mean.
b) No, because the standard error of the mean is higher than the critical value.
c) Yes, because the t-value is greater than the critical value.
d) No, because the sample size is too small to draw conclusions.
