- An analyst in the real estate business is interested in the relationship between the cost of the monthly rent of an apartment and the size of an apartment, in big cities. She gathers data for apartment buildings in 12 cities in 12 different states. In each city, she gets the numbers for at least 5 different buildings and at least 40 apartments in each building. She reaches the following conclusion: the rental cost of a 2-bedroom apartment is 50% more than the rental cost of a 1-bedroom apartment, and the rental cost of a 3-bedroom apartment is 50% more than the rental cost of a 2-bedroom apartment. Based on the paragraph, what is the minimum number of apartments she collected data on? Do you think her sample was large enough to be statistically valid? Based on the paragraph, are there any apartments or apartment buildings that she would have excluded from her study? Do you see any bias in how she selected apartments for her study? Based on the paragraph, is there a positive…Jo, a store owner, has an option of selling hot drinks or halu-halo during a championship game. The profits will depend on weather conditions.

It was learned that during the time of the year 65% of the days are clear and 35%) are rainy. What type of refreshments should the owner sell? Make a decision tree and state your decision.A commuter owns 2 cars, 1 compact and 1 standard model. About ¾ of the time he uses the compact to travel to work, and about ¼ of the time the larger car is used. When he uses the compact car, he usually gets home by 5:30 p.m. about 75% of the time; if he uses the standard-sized car, he gets home by 5:30 p.m. about 25% of the time (but he enjoys the air conditioner in the larger car). a) If he gets home at 5:35 p.m., what is the probability that he used the compact car? b) If he gets home at 5:30 p.m., what is the probability that he used the standard model?

After a person becomes infected and then recovers, the person is immune (cannot become infected again). Of the people who are infected, 2% will die each year and the others will recover. Of the people who have never been infected, 20% will become infected each year. How many people will be infected in 4 years? (Round your answer to the nearest whole number.)___________ people.
