A sample of size 47 will be drawn from a population with mean 19 and standard deviation 14. Find the probability that will be greater than 22.
Solutions
Expert Solution
Solution :
Given that ,
mean = 
= 19
standard deviation = 
= 14
=
/ 
n = 14 /
47 = 2.0421
P(
> 22) = 1 - P(
< 22)
= 1 - P[(
- 
) /
< (22 - 19) / 2.0421]
= 1 - P(z < 1.47)
= 1 - 0.9292
= 0.0708
Probability = 0.0708
