adding two negative integers always yields a negative sum
Urn 1 = 4 green balls and 6 blue balls, a total of 10 balls
Urn 2 = 6 green balls and 2 blue balls, a total of 8 balls.
Probability of blue balls:
Urn 1 : P = 6/10
Urn 2 : P = 2/8
Probability that both balls are blue:
6/10 * 2/8 = 6*2 / 10*8 = 12/80 = 6/40 = 3/20
Answer is B. 3/20

I know that the value of the test statistic is z= -1.00 given the information I just read from your upload.
I want to say B. Fail to Reject Null Hypothesis
But I'm not a 100% sure it's actually B
