Short Answer

Expert verified

The value of80thpercentile is60.3048

Step by step solution

01

Given Information

Given that,

X~N(54,8)

Where,

渭=54

蟽=8

02

Explanation

Now,80thpercentile can be calculated

below:

P(x<k)=Px-渭蟽<k-渭蟽

0.80=PZ<k-548

k-548=0.7881From standardnormal table

k-54=0.7881脳8

k=6.3048+54

localid="1649333427174" k=60.3048
