Question 1157910
b. When Ho is p1=p2, I want Ha to be everything else, which is p1 NE p2

c. It is 21/194 or 0.1082

d. this is (0.1082-.080/0.0195, The difference of means divided by the SE. It is 1.45.
The p-value is 0.1470

e. This means that such a result could happen by chance 0.1470 of the time if the true value were 0.08. We fail to reject Ho because the p-value is greater than alpha.  That is b.  We don't accept the null hypothesis but rather say we are unable to reject it. Not guilty vs, innocent analogy.
