Answer:
1.04%
Step-by-step explanation:
Using the z-score formula, we have:
z = (X - P) / σ
z = score
x = given value
P = average
σ = standard deviation
Z = (40 - 43.7) / 1.6 = 2.31 > <u>0.9896</u> (tabulated in the z-table)
Now, with that number, we find the probability that a randomly selected worker works less than 40 hours per week.
1 - 0.9896 = 0.0104 * 100 = 1.04%

x² = 144 ( take the square root of both sides )
x = = 12 → B
