- Once a computer worm infects a personal computer via an infected e-mail message, it sends a copy to 25-e-mail addresses it finds in the electronic message mailbox on this personal computer. What is the maximum number of different infected computers in the time it takes for the infected message to be forwarded six times? Note: You should count the total of infected computers including the initial one.The mtcars data set contains data on 32 cars from the 1974 Motor Trend US magazine. The data set has 11 variables that measure different aspects of the cars, such as miles per gallon (mpg), horsepower (hp), weight (wt), and number of cylinders (cyl). The data set can be used to study the relationship between fuel consumption and car performance, as well as other factors that affect the efficiency and design of the cars. What is the maximum and minimum number of the range regarding the explanatory variable for which the regression model can make valid predictions?For numbers 24-26: Aquascaping involves growing aquatic plants and aesthetically arranging them in an aquarium like a natural landscape. Success of growing plants depends on several factors such as light condition, water pH, and carbon dioxide level. It is of interest to determine if varying concentrations of carbon dioxide (0.5 ppm, 1.2 ppm, 1.5 ppm) introduced to an aquarium will promote or deter an aquatic plants' growth. Ten aquariums with one-week old plant were set-up and randomly assigned to each treatment.

- A researcher believed that the number of rental cars in service by a car rental company would have an impact on the total annual revenue for that car rental company. Five small car rental companies were surveyed, with the number of Cars in service recorded in units of 1000 (so if a car rental company had 54000 cars in service, a 54 would be recorded) and Annual Revenue measured in millions of dollars (so an Annual Revenue of $10,000,000 would be recorded as 10).
