What are you supposed to do ?

(B) 8

Explanation:

Given:

Mean, μ = 34

Standard deviation, σ = 9

Data points, x = 20, 22, 24, 28, 33, 35, 38, 40, 42, 45, 47

We can calculate the z score by the formula

z(20) =

z(22) =

z(24) =

z(28) =

z(33) =

z(35) =

z(38) =

z(40) =

z(42) =

z(45) =

z(47) =

Z score less than 0.7 is 8

i think asking google will you get the answer to that question
