A scientist has measured quantities y, x1,and x,. She believes that y is related to x, and x2
through the equation y = ae+Px2 8, where & is a random error that is always positive. Find
a transformation of the data that will enable her to use a linear model to estimate B, and B,.
A new town was incorporated in 1960. The size of the town's population
was recorded every 5 years after 1960. Using the variables x, for number of
years since 1960, and y, for the size of the population, three models were
created to predict the population from the number of years since 1960.
a. Fit a linear regression equation
b. Compute for r

This time the merchant has on hand 30 kilograms of Colombian beans, 15 kilograms of Kenyan beans, and 15 kilograms of French roast beans. Suppose one bag of the house blend produces a profit of $0.50, one bag of the special blend produces a profit of $1.50, and one bag of the gourmet blend produces a profit of $2.00. How many bags of each type should the merchant prepare if he wants to use up all of the beans and maximize his profit? What is the maximum profit?arrow_forwardA multiple regression model has the form y with hat on top= 12 – 4 x1 + 5 x2. As x1 increases by 7 units (holding x2 constant), y with hat on top is expected to (enter increase, decrease) by units.arrow_forward
- From 2000 through 2009, the population of State A grew more slowly than that of State B. Models that represent the populations of the two states are given by P = 37.5t + 6075 State A P = 168.2t + 5138 State B where P is the population (in thousands) and t represents the year, with t = 0 corresponding to 2000. Use the models to estimate when the population of State B first exceeded the population of State A. (Round your answer to the nearest year.)arrow_forwardThe same disease is spreading through two populations, say Pi and P2, with the same size. You may assume that the spread of the disease is well described by the SIR model. dSa - BaSaIa dt dla - dt dRa YaIa dt with Sa(0) + I.(0) + R.(0) = N where N denotes the fixed population size. The subscript a identifies the population P or P2. For example, if a = 1, the variables are related to P1. Assume that S1 (0) = S2 (0) and I1(0) = I½(0) and that no interventions such as quarantine or vaccination have been implemented. If the difference in the spread of the disease is due only to the poor over-all health of a population, which population has the best over-all health of the two populations? - Susceptible Population 1 - Susceptible Population 2 700 600 500 400 300 200 100 10 15 20 t P1.

If 30 vehicles cross the bridge during a particular daytime period, what is the resulting expected toll revenue? [Hint: Let X = the number of passenger cars; then the toll revenue h(X) is a linear function of x.]arrow_forward
