TOPIC: Linear Regressionplease answer, will upvote your solutions. An article in Wear (1992, Vol. 152, pp. 171-181) presents data on the fretting wear of mild steel and oil viscosity. Representative datafollow with x = oil viscosity and y = wear volume (10*cubic millimeters).y 240 | 181| 1931551721101137594x 1.6 9.4 15.5 20.0 22.0 35.5 43.0 40.5 33.0Round your answers to two decimal places (e.g. 98.76).(a) Construct a scatter plot of the data. Does a simple linear regression model appear to be plausible?O YesO No(b) Fit the simple linear regression model using least squares. Find an estimate of .(c) Predict fretting wear when viscosity x= 30.(d) Obtain the fitted value of y whenx= 22.0 and calculate the corresponding residual.

Flying twice as farA flight from Los Angeles to ABQ is about 2 hours but is 670.2 miles.A flight from San Jose to Chicago is 4 hours but is 1859.0 miles.Can anyone explain why the travel time from San Jose to Chicago is notlonger and closer to 5.75 hours?If the distance increase by 2, shouldnt the time increase by a factorof 2 as well?1. Write a linear model for this question. Takeoff and landing will take a fixed amount of time. Actualtravel in the air will take time proportional to the distance traveled. Think about which of thevariables (time and distance) is the independent variable, and identify the slope and intercept withtheir units.2. Use the data in the quotation to estimate the two constants in your linear model.

Degrees Earned The number of postsecondarydegrees earned, in thousands (including associate’s,bachelor’s, master’s, first professional, and doctoral degrees), can be modeled by y = 3.980x2 -17.597x + 2180.899, where x is the number of yearsafter 1990. If this model is accurate, during what yearsfrom 1990 on would the number of postsecondarydegrees earned be less than 3500 thousand?
