Answer: C
Step-by-step explanation:
Rejecting the null hypothesis means we've found a significant difference in the means. That means the probability that we'd see means so far apart by chance is less than our threshold of significance.
Probability is all about multiplying fractions.
The first fraction is the probability of picking a girl.. so how many of the 12 total children are girls. (8/12)
The second fraction is the probability of picking a boy.. so how many of the 11 remaining children are boys. (4/11)
8/12 X 4/11 = 8/33 -> this isn't even an option but I'm like 10000% this is the right answer..
I started off this answer feeling so confident lol. good luck.
Multiply 4 by 24 and get 6 then multiply 6 by 6 and get 36
A = 36
