You believe the population is normally distributed, but you do not
know the standard deviation. You obtain a sample of size n=8n=8
with a mean of M=49.9M=49.9 and a standard deviation of
SD=7.8SD=7.8.
What is the critical value for this test? (Report answer accurate
to three decimal places.)

You believe the population of difference scores is normally
distributed, but you do not know the standard deviation. You obtain
pre-test and post-test samples for n=20n=20 subjects. The average
difference (post - pre) is ¯d=−7.1d¯=-7.1 with a standard deviation

You obtain 338 successes in a sample of size n1=374n1=374 from the
first population. You obtain 535 successes in a sample of size
n2=624n2=624 from the second population. For this test, you should
NOT use the continuity correction, and you should use the normal
distribution as an approximation for the binomial
distribution.
What is the test statistic for this sample? (Report answer accurate
