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.
