Question

Hello would like to see if you help me with question 3 a or b? I started working on it but not sure about the answer

Answer 1

Given:

a) z=-0.7

To find the area below z = -0.7,

$P(z<-0.7)=0.24196$

b) the area above z = -1.1.

$\begin{gathered} P(z>-1.1)=1-P(z<-1.1) \\ =1-0.13567 \\ =0.86433 \end{gathered}$

Answer: a) 0.24196 b) 0.86433
