You believe both populations are normally distributed, but you do
not know the standard deviations for either. However, you also have
no reason to believe the variances of the two populations are not
equal. You obtain a sample of size n1=25 with a mean of M1=77.7 and
a standard deviation of SD1=11.4 from the first population. You
obtain a sample of size...

Ho:p1=p2
Ha:p1<p2
You obtain 96% successes in a sample of size n1=375 from the first
population. You obtain 99.1% successes in a sample of size n2=222
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.

You obtain a sample from the first population with 193 successes
and 355 failures. You obtain a sample from the second population
with 303 successes and 464 failures. For this test, you should NOT
use the continuity correction, and you should use the normal
distribution as an approximation for the binomial
distribution.
