<PRE><B>Question 563291</B>
I am struggling with several questions any help would be greatly appreciated I just cant seem to figure these out. 
1) Two events A and B are mutually exclusive if the probability that A or B occurs is the sum of the probability that A occurs with the probability that B occurs. 

2)A correlation coefficient of 0.96 would mean that the values of x increase as the values of y decrease. True or False?
That condition would cause you to have a negative correlation coefficient.
------------------------------------------ 
3) What is the value for a 98% confidence interval when n=12? 
A) 23.053
B) 24.725 
C) 25.090 
D) 24.278 
Ans: Insufficient information.
