Answer:
Choice D. 15.2%
Step-by-step explanation:
We have a normal...
mean u = 48
standard deviation s = 2
We want P(43 < X < 46)
We standardize.
Consider P(43 < X) = P( (43 - 48)/2 < Z) = P(-2.5 < Z)
P( X < 46) = P( Z < (46 - 48)/2 ) = P(Z < -1)
We want P( -2.5 < Z < -1)
Look at Z-scores.
P( Z < -2.5) = 0.0062
P(Z < -1) = 0.1587
so P(-2.5 < Z < -1) = P(Z < -1) - P(Z < -2.5) = 0.1587 - 0.0062 = 0.1525 = 15.2%

A) Dependent Variable = Sue's Earning
Independent Variable = Number of hours she work
Y = 6x
B) When, x = 1, y = 6(1) = 6,
when x = 2, y = 6(2) = 12
when x = 3, y = 6(3) = 18
Ordered pairs would be: (1, 6), (2, 12), (3, 18)
C) Equation would be: Y = 6x
Where, y = Earning
x = number of hours
