At a large company, the salaries (y, in thousands of dollars)
and years of experience (x) of six randomly chosen engineers
are:
x (years) 6 7 9 10 13 15
y (salary) 44 41 43 45 51 49
Compute the least squares regression equation and use that
equation to predict the salary (in thousands of dollars) of a new
employee with 8 years of experience,
Following are age and price data for 10 randomly selected cars
between 1 and 6 years...
Following are age and price data for 10 randomly selected cars
between 1 and 6 years old. Here, x denotes age in, in years, and y
denotes price, in hundreds of dollars. Use the information to
complete parts (a) through (g).
x : 6,6,6,2,2,5,4,5,1,4
y: 280,285,305,425,389,325,355,328,415,330
Predict the value of the response variable for a 22-year-old
car and a 33-year-old car, and interpret your results.
For a 22-year-old car, the predicted price is $ _____
For a 33-year-old car, the...
