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.
