Question: In 2009, the mean score of participants from Minnesota in SAT Critical Thinking test is 595 with variance of 11025. If a sample of sixty participants were to be taken from this group, what is the probability that the mean is: (a) less than 572? (b) between 577 and 590? (c) greater than 610?
- = 0.0449
- = 0.264
