Answer:
[tex] P(z<1.13) = 0.8708[/tex]
And the best option would be:
[tex] 0.8708[/tex]
Step-by-step explanation:
We assume that the distribution for the random variable is:
[tex] X \sim N (\mu=0 , \sigma=1) [/tex]
For this case we want to calculate the following probability:
[tex] P(z<1.13)[/tex]
And we can use the normal standard distribution or excel and we got:
[tex] P(z<1.13) = 0.8708[/tex]
And the best option would be:
[tex] 0.8708[/tex]
