It's one of the questions in my business statistics homework. i'm not so good in statistics, i swear i've spent many hours figuring out the answer to this question but i cannot come up with one.

Can somebody who's good in business statistics please kindly anwser the question for me? Also please show the mathematical solution?

here it is:

The American Council of Life Insurance and the Life Insurance Marketing and Research Association have reported that insured households with heads 35 to 44 years old had an average of $95,900 of life insurance coverage. Assuming a normal distribution and a standard deviation of $25,000, what's the probability that a randomly selected household with a head in this age group had less than $70,000 in life insurance coverage?

Thanks very much.

Z =

= X - (mean)
-----------
SD

= 70,000 - 95,900
-----------------
25000

= -1.036

Z < -1.036

Therefore Z > 1.036 (rounded to 1.04)

P (X < 70,000)
= P (Z > 1.04)
= 1 - 0.8508
= 0.1492

done!

n btw, thanx my bf for this.

p/s : double check.

oh, how old r u??
