Lactose intolerance Lactose intolerance causes difficulty
in digesting dairy products that contain lactose (milk sugar). It is particularly common among people of African and Asian ancestry. In the United States
(ignoring other groups and people who consider themselves to belong to more than one race), of the population is white, 14% is black, and is
Asian. Moreover, of whites, of blacks, and of Asians are lactose intolerant.
(a) What percent of the entire population is lactose intolerant?
(b) What percent of people who are lactose intolerant are Asian?
Who eats breakfast? The two-way table describes the 595 students who responded to a school survey about eating breakfast. Suppose we select a student at random. Consider events B: eats breakfast regularly, and : is male.
(a) Find Explain what this value means.
(b) Find Explain what this value means.
Get rich Refer to Exercise 63.
(a) Find P(鈥渁 good chance鈥� | female).
(b) Find P(鈥渁 good chance鈥�).
(c) Use your answers to (a) and (b) to determine whether the events 鈥渁 good chance鈥� and 鈥渇emale鈥� are
independent. Explain your reasoning.
Simulation blunders Explain what鈥檚 wrong with each of the following simulation designs.
(a) A roulette wheel has colored slots鈥� red, black, and green. To simulate one spin of the wheel, let numbers to represent red, to
represent black, and to represent green.
(b) About of U.S. adults are left-handed. To simulate randomly selecting one adult at a time until you find a left-hander, use two digits. Let to represent being left-handed and to represent being right-handed. Move across a row in Table D, two digits at a time, skipping any numbers that have already appeared, until you find a number between and 10. Record the number of people selected.
Color-blind men Refer to Exercise . Suppose we randomly select U.S. adult males. What鈥檚 the probability that at least one of them is red-green
color-blind? Design and carry out a simulation to answer this question. Follow the four-step process.
