Suppose that a sample of size 100 is to be drawn from a population with standard deviation L0. a. What is the probability that t
he sample mean will be within 2 of the value of p?
1 answer:
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.
