SVEN [57.7K]

Answer:

Hence the probability that the mean of their utility bills will be less than $75 = P(X < 75) is 0.9736.

Step-by-step explanation:

Now,

Population mean electric bill, $\mu =$ $72

Population standard deviation, $\sigma =$ $6

Standard error of the mean $= \sigma / \sqrt{n} = 6 / \sqrt{15} = 1.5492$

The probability that the mean of their utility bills will be less than $75 = P(X < 75)

= P[Z < (75 - 72) / 1.5492]

= P[Z < 1.9365]

= 0.9736 (Using Z table)
