n a large clinical trial, 396 comma 651 children were randomly assigned to two groups. The treatment group consisted of 198 comma 747 children given a vaccine for a certain disease, and 37 of those children developed the disease. The other 197 comma 904 children were given a placebo, and 111 of those children developed the disease. Consider the vaccine treatment group to be the first sample. Identify the values of n 1, ModifyingAbove p with caret 1, ModifyingAbove q with caret 1, n 2, ModifyingAbove p with caret 2, ModifyingAbove q with caret 2, p overbar, and q overbar.

I guess you want to find the relative frequencies:

In total, we have 396,651 children

in sample 1, we have 198,747 children, and of those, only 37 developed the disease.

This means that the vaccine is not effective in:

p = 37/198,747 = 0.00019

For the placebo, we have a sample of 197,904 children in total, and 111 of them developed the disease, then we have a probability of the placebo not being effective is:

p = 111/197,904 = 0.00056

So we can see that the difference is significant, meaning that the placebo is not effective in more than twice the cases where the vaccine is not effective.

do you have a picture of the table

the answer would be a 24
