- The table describes weekly usage of an appliance is proportional to its Maintenance expense, is that correct? Use regression model to discuss your answer.Regression methods were used to analyze the data from a study investigating the relationship between roadway surface temperature (x) and pavement deflection (y). The simple linear regression model is y = 0.33 + 0.0042x. (a) Suppose that temperature is measured in °C rather than °F. Determine regression coefficients for the new model y = Bo +B1x. Round your answer to two decimal places (e.g. 98.76). Bo Round your answer to four decimal places (e.g. 98.7654). (b) What change in expected pavement deflection is associated with a 1°C change in surface temperature? Round your answer to four decimal places (e.g. 98.7654).

- In multiple regression, you can have nominal and continuous predictors true or falseResidual analysis is important when studying the potential for linear regression because it allows for assumptions to be ignored for a time while graphs are created. True O FalseThe fitted regression Computer power dissipation=14.82 +0.049 Microprocessor speed, where Computer power dissipation is measured in watts and Microprocessor speed is measured in MHz. (a-1) If Microprocessor speed = 1 MHz, then Computer power dissipation = (a-2) Choose the correct statement. (b) O An increase in the microprocessor speed decreases the computer power dissipation. O An increase in the microprocessor speed increases the computer power dissipation. O A decrease in microprocessor speed increases the computer power dissipation. If Microprocessor speed = 2,900 MHz, then Computer power dissipation = watts. (Round your answer to 3 decimal places.) (c) Choose the right option. watts. (Round your answer to 2 decimal places.) O The Intercept would be meaningful because you would have a computer with zero speed. O The Intercept would not be meaningful because you would not have a computer with zero speed.
- Give examples of where the use of regression analysis can be benificially be made.A particular article used a multiple regression model to relate y = yield of hops to x, = average temperature (°C) between date of coming into hop and date of picking and x, = average percentage of sunshine during the same period. The model equation proposed is the following. y = 415.11 – 6.6x1 – 4.50x2 +e (a) Suppose that this equation describes the actual relationship. What mean yield corresponds to a temperature of 20 and a sunshine percentage of 40? (b) What is the mean yield when the average temperature and average percentage of sunshine are 19 and 44, respectively?Use the cubic regression model above to answer this question.
