Question

x is a normally distributed random variable with a mean of 1, and p(-4 12 years ago

Answer 1

p(-4<x<-2)=p(4<x<6)

Answer 2

is that the answer?

Answer 3

if so , how you figure?

Answer 4

it is not the final answer...it will lead you to the answer though

Answer 5

how if It doesnt show me the standard deviation

Answer 6

you don't need the standard deviation to answer this problem

Answer 7

all I know is that the intervals |-4,-2| |4,6| are symmetric, but I cant figure the answer.

Answer 8

do you agree that p(-4<x<-2)=p(4<x<6)?

Answer 9

no because one is negative and the other is positive. right?

Answer 10

well they are the same...using this fact we can get ...


p(-4<x<-2)+p(4<x<6)=.2

p(-4<x<-2)+p(-4<x<-2)=.2

2*p(-4<x<-2)=.2

p(-4<x<-2)=.1

Answer 11

I have to find that formula. That makes so much sense. thanks.

Answer 12

is this the final answer?
