Assume that the random variable X is normally distributed, with mean ? = 50 and standard deviation ? = 7. Compute the following

sineoko [7]

Answer:

Step-by-step explanation:

Given that the random variable X is normally distributed, with

mean = 50 and standard deviation = 7.

Then we have z= $\frac{x-50}{7} is N(0,1)$

Using this and normal table we find that

a) $P(56$

b) When z=0.02

we get

$x=50+0.02(7)=50.14$

c) 90th percentile z value =1.645

90th percentile of X $=50+7(1.645)\\= 50+11.515\\=61.515$
