Question

Let Z be a standard normal random variable. Use the calculator to determine the value of c such that:

Answer 1

\[P(Z \le C)=0.1492\]

I really thought I had this one, as I came up with C= -1.04, but it is not accepting the answer. Am I doing something wrong here?

Answer 3

hmm i get the same thing ....

Answer 4

i fluttering hate statistics

Answer 5

this is driving me nuts. Its DOES also say this:

Carry your intermediate computations to at least four decimal places. Round your answer to at least two decimal places.

But I could have sworn that's what I was doing..

Answer 6

i got the same thing, so i can't really add anything

Answer 7

Thank you anyhow! You've been such an amazing help since I joined this website.

Answer 8

was the .1492 given or did you have to calculate that somehow ?

Answer 9

the .1492 was given

Answer 10

then i get -1.03987...

or -1.04 rounded

maybe there is a typo in the problem or solution

Answer 11

When I enter -1.04 it just blanks out and won't submit. Maybe I should try -1.03987? Its just that it told me to round "at least two decimal spaces"

Answer 12

i find it weird they say "Carry your intermediate computations to at least four decimal places."

Answer 13

you wrote " Use the calculator ..."

is there a specific calculator you are supposed to use since you wrote "the" and not not "a" calculator

Answer 14

you can try

Answer 15

it's the calculator provided through ALEKS but it's nonsense.

Answer 16

i'm not familiar with that

Answer 17

I don't know, even when I've gotten a question wrong before it's accepted the answer and just marked it wrong. This time it's not even accepting it, which usually only happens if it's a format they don't accept for the question. Like if they don't accept a negative number as an answer, etc.

Answer 18

Answer 19

maybe you should contact your instructor and address this issue with them

Answer 20

I have half a mind to just skip this question but I would really like to get it right!! haha. I will contact them, thank you :)

Answer 21

Answer 22

i used the calculator i linked to above and got exactly the same answer
