Question 251363: Populations 1 and 2 are considered. The null and alternative hypothesis are:
H0:m1=m2
H0:m1≠m2
Random samples are taken from each population , with n1 =100 and n2=11 sampled from population 1 and 2. Observations of success are 60 from population 1 and 5 from population 2(S1=60;S2=5), with sample standard deviations of 5.2 and .62. An estimated of the standard deviation of the differences is approximately?

Your hypotheses imply you are testing means, but you are
asked for a conclusion regarding standard deviation.
Which is it? means or std's.
