Question

standard normal variable, find the probability P(z> 0.59)

Answer 1

1 - z(0.59)

Answer 2

just gotta table up the z(0.59)

Answer 3

or negate the z, and find the table value of z(-0.59)

Answer 4

How do i what z is? thanks

Answer 5

I will put in the entire problem. the probability that z lies between -2.41 and z and 0
P(z>0.59) thanks

Answer 6

do you have a calculator, perhaps a ti83? if not, there are ztables written up that can be utilized

Answer 7

the probability that z lies between -2.41 and 0 is the cumulative probability from -2.41 to 0 of a mean of 0 and sd of 1

Answer 8

i have a t-83

Answer 9

under that stats button, you can hit the normalCDF function

Answer 10

did that

Answer 11

that function takes 4 arguments: lower, upper, mean, sd

Answer 12

to find the cumulative probability of z, from -2.41 to 0

normalCDF(-2.41,0,0,1) is the inputs

Answer 13

with any luck, you should get about .492

Answer 14

to find the cumulative probability of z > 0.59, its the same function

lower is .59 and upper is say 9999 for some arbitrarily large upper value

Answer 15

ok, got the .492 and used it as the z score but is coming upw thi different answer
what is p(z > .59)

Answer 16

z>.59 is about .2776 from the tables

Answer 17

ok, thanks you are best

Answer 18

youre welcome :)
