Question

Statistics:

\[\mu=28\]
\[\sigma=5\]
If \[P(z\le z_0)=0.12\]
How do I use the attached table to come to the conclusion that \[z_0=-1.175\]?

Answer 1

look up .12 in the middle of the table

Answer 2

or the numbers closest to .12

Answer 3

You mean here?

Answer 4

no...the middle of the table...middle of the paper

Answer 10

here?

Answer 11

yes...but there is another number that is really close to .12

Answer 12

.1190

Answer 13

yes...what are the z values for those 2 numbers

Answer 14

but how did they come to the conclusion that z_0=-1.175?

Answer 15

answer my last question first

Answer 16

-1.1 and .07 and .08....ah I see
Therefore -1.75 since it between .1190 and .1210

Answer 17

-1.17 and -1.18 take average of the two gives -1.175
