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.
Answer:
it's 1130.97
Step-by-step explanation:
V = A h.
Since the area of a circle = π r 2 , then the formula for the volume of a cylinder is:
V = π r 2 h.
