The mean household income for a certain state is $69,000 with a standard deviation of $10,000. assuming a normal distribution, about 95% of all households have an income over what amount?

a.$49,000
b.52,551
c.60,000
d.85,449
e.$89,000

B.52,551

Step-by-step explanation:

Use a z-table to find the corresponding z-score.

P(z>Z) = 0.95

P(z<Z) = 0.05

z = -1.645

Now find the corresponding income:

z = (x − μ) / σ

-1.645 = (x − 69000) / 10000

x = 52550

you probably already have the answer but anyways it's b. 15.0
