In 2010 (with ~320 million people occupying 124.5 million homes nationwide), there were slightly more than 888,000 burglaries in a residence.
a. What is the probability your home will be broken into within the next year?
b. If your home is in a development of 100 homes, what number of break-ins can you expect in the next 20 years?

4-100 Phoenix water is provided to approximately 1.4 million people who are served through more than 362,000. All accounts are metered and billed monthly. The probability that an acoount has an error in a month is 0.001, and accounts can be assumed to be independent. (a) What are the mean and standard deviation of the number of account errors each month? (b) Approximate the probability of fewer than 340 errors in a month (c) Approximate a value so that the...
Question 12 of 13 > According to CDC estimates, more than two million people in the United States are sickened each year with antibiotic-resistant infections, with at least 23,000 dying as a result. Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next generations of microbes, it is a very serious public health problem. Of the three infections considered most serious by the CDC, gonorrhea has an...
More than 100 million people around the world are not getting
enough sleep; the average adult needs between 7.5 and 8 hours of
sleep per night. College students are particularly at risk of not
getting enough shut-eye. A recent survey of several thousand
college students indicated that the total hours of sleep time per
night, denoted by the random variable X, can be approximated by a
normal model with E(X) = 6.94 hours and SD(X) = 1.23 hours.

According to CDC estimates, more than two million people in the United States are sickened each year with antibiotic-resistant infections, with at least 23,000 dying as a result. Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next CDC, gonorrhea has an estimated 800,000 cases occurring annually, with approximately 30% of those cases resistant to any antibiotic. Assume a physician treats 7 cases of gonorrhea during a...

Oil prices rose more than 20% this year but there were no sharp spikes and crude futures barely sniffed $70 a barrel despite attacks on the world’s biggest oil producer, sanctions that crippled crude exports of two OPEC members and gigantic supply cuts from big oil producing countries. The price gains in crude oil benchmarks were all in the first quarter of 2019, even as the next several months featured supply shocks that in the past would probably have propelled...
