A sample of size 47 will be drawn from a population with mean 28 and standarddeviation 6. Find the probability that x will be greater than 29.
A)0.1423B)0.1003C)0.8729D)0.1271
Solutions
Expert Solution
Solution :
=
/ 
n = 6 /
47 = 0.8752
P(
> 29) = 1 - P(
< 29)
= 1 - P[(
- 
) /
< (29 - 28) / 0.8752]
= 1 - P(z < 1.14)
= 1 - 0.8729
= 0.1271
Probability = 0.1271
option D) is correct
