Answer:
No
Step-by-step explanation:
If the graph of a relationship is a line or a ray through the origin, then it is proportional. If it is a line or ray that does not pass through the origin, then it is not proportional. Also, if it is not linear, then it is not proportional.
In order to be proportional the graph must be a straight line that always passes through (0,0).

Answer:
The probability that the sample mean will lie within 2 values of μ is 0.9544.
Step-by-step explanation:
Here
- the sample size is given as 100
- the standard deviation is 10
The probability that the sample mean lies with 2 of the value of μ is given as
Here converting the values in z form gives
Substituting values
From z table
So the probability that the sample mean will lie within 2 values of μ is 0.9544.
