Answer: substancially lower / more to the left
If the data is skewed to the left the mean will be moved more to the left so it will decrease. The mean is greatly changed by the skew of the data
Answer:
The probability that the total loss, X + Y is less than 2 is P=0.235
Step-by-step explanation:
We know the joint density function:

To find the probability that (X+Y)<2, we can divide this in two steps.
- When X=0, Y should be less than 2. This is P(X=0,Y<2).
- When X=1, Y should be less than 1. This is P(X=1, Y<1).
We can calculate P(X=0,Y<2) as:

We can calculate P(X=1,Y<1) as:

Then

Answer:
1+1=2
Step-by-step explanation:
Answer:
Hi,
Step-by-step explanation:
(13,7,4) may not be a triangle since 13 is not little than 7+4=11
(7,10,8,) may be a triangle (7 < 10+8 , 10 < 7+8, 8 < 10+7)
(9,4,4) no since 9 is not < 4+4
(2,8,12) no since 12 is not < 2+8
The only answer is (7,10,8)
