Tire pressure (psi) and mileage (mpg) were recorded for a random sample of seven cars of thesame make and model. The extended data table (left) and fit model report (right) are based on aquadratic model Write out the estimated quadratic polynomial regression model.
The population of a certain country was approximately 5050 million in 1900,175175 million in 1950, and 350350 million in 2000. Construct a model for this data by finding a quadratic equation whose graph passes through the points (0,5050), (5050,175175), and (100100,350350). Use this model to estimate the population in 2050.
According to the data reported by the New York State Department of Health regarding West Nile Virus for the years 2000-2008, the least squares line equation for the number of reported dead birds (x) versus the number of human West Nile virus cases (y) is y=−10.2638+0.0491x. If the number of dead birds reported in a year is 732, how many human cases of West Nile virus can be expected? Also we know r=0.5490. No prediction can be made. 19.6 26 38.1

Suppose the U.S. Census Bureau projects the population of Colorado to be 4.3 million in 2000 and 6.1 million in 2020. Assuming the population growth is linear, Use t years since 1999 and p the population of Colorado in millions. According to your linear model, what is the population of Colorado in 2033? {final answer will be decimal number with two decimal places only}

The annual expenditure for cell phones varies by the age of an individual. The average annual expenditure E(a) (in $) for individuals of age a (in years) is given below:a: 20, 30, 40, 50, 60, 70E(a): 502, 658, 649, 627, 476, 2131. Use quadratic regression to find the model that best represents the data.2. At what age is the yearly expenditure for cell phones the greatest? Round the answer to the nearest year. YOU MUST SHOW THE WORK FOR THIS PART!
A biologist wants to predict the height of male giraffes, y, in feet, given their age, x1, in years, weight, x2, in pounds, and neck length, x3, in feet. She obtains the multiple regression equation yˆ=7.36+0.00895x1+0.000426x2+0.913x3. Predict the height of a 12-year-old giraffe that weighs 3,100 pounds and has a 7-foot-long neck, rounding to the nearest foot.

A particular article proposed a quadratic regression model to describe the relationship between x = degree of delignification during the processing of wood pulp for paper and y = total chlorine content. Suppose that the actual model is the following. y=245+ 75x-4x² + e (a) Mean chlorine content for x = 6 is ---Select--- mean chlorine content for x = 8. (b) What is the change in mean chlorine content when the degree of delignification increases from 8 to 9? What is the change in mean chlorine content when the degree of delignification increases from 12 to 13?
Use Excel to Run the Regressions:1. Wage and Age: Do you think a worker’s wage is related to his/her age? It is expected that wagesincrease with age up to certain age, after that wages go down. The “Wage Quadratic Data” fileposted contains data on the hourly wage (in $) for construction workers, workers’ ageand whether the worker has a bachelor’s degree or not (Graduate equals 1 if the worker has abachelor’s degree and 0 otherwise). Use the data file to answer the following questions:A) Build a model to predict the hourly wage of construction workers based on their education andage.B) Use the model to predict the hourly wage for a college graduate construction worker if his/herage is 30, 50, and 70c) Based on your model, calculate the age at which the hourly wage for construction workers ismaximized.
A biologist collected data on a sample of 20 porcupines. She wants to be able to predict the body mass of a porcupine (M, in grams) based on the length of the porcupine (L, in cm).
