Answer 1

Answer:

The probability that a data value in a normal distribution is between a

z-score of -1.32 and a z score of 1.32 is 81.3%

Option D is correct.

Step-by-step explanation:

We need to find the probability that a data value in a normal distribution is between a  z-score of -1.32 and a z score of 1.32.

We can write it as P(-1.32 < Z < 1.32)

It is equal to : $P(-1.32 < Z < 1.32)= P(Z$

Looking at z-score tables to find value of z=1.32 and z=-1.32

P(Z<1.32)= 0.90658

P(Z<-1.32) = 0.09342

Putting values and finding answer

$P(-1.32 < Z < 1.32)= P(Z$

So, the probability that a data value in a normal distribution is between a

z-score of -1.32 and a z score of 1.32 is 81.3%

Option D is correct.
