Question

1

In a normal distribution, what is the probability that a data value will fall above the
data value associated with a z-score of 0.15?
A 55.96%
B 53.98%
C 44.04%
D 46.02%

Answer 1

Answer: C 44.04%

Explanation:

in a normal distribution,

P(Z>z)= 1-P(Z<z) (*)

Here , we need to find : P(Z>0.15)

By using (*) , P(Z>0.15)=1- P(Z<0.15)

= 1- 0.5596 [By p-value table]

= 0.4404

= 44.04% [multiply 100 to convert into percent]

∴ the probability that a data value will fall above the data value associated with a z-score of 0.15 = 44.0%

hence, correct option : C 44.04%
