A trucking company tries to determine the factors affecting total daily traveling time for one of its driver(hours). X1 = distance traveled (miles) and X2 = the number of deliveries measured for a sample of 20drivers. Data scientists tried a F test to determine if the total daily traveling time has a significant linearrelationship with X1 and/or X2. If you know F value is 10, do you think if there is significant linearrelationship? a = 0.05O No, there is not significant linear relationship since p-value is in (0.1,0.5).O No, there is not significant linear relationship since p-value is in (0.05,0.1).O Yes, there is significant linear relationship since p-value is in (0.01,0.05).O Yes, there is significant linear relationship since p-value is in (0.001,0.01).

The figure plots the number of manatee deaths by boat versus the number of boats registered to Florida and thousands. There is a clear straight line pattern with a modest amount of scatter. The correlation between these variables is R equals 0.94. What percentage of the observed variation among the manatee deaths by boats is explained by the straight line relationship between manatee deaths and number of boats registered?

ologist was recording various temperatures (in degrees Celsius) and predicting the amount of glucose produced by a plant (in milligrams). Suppose the linear equation was the following: ?̂ = 12.7 − 0.223? Suppose the correlation coefficient was −0.12. How would you classify the correlation between temperature and amount of glucose?
While attempting to measure its risk exposure for the upcoming year, an insurance company notices a trend between the age of a customer and the number of claims per year. It appears that the number of claims keep going up as customers age. After performing a regression, they find that the relationship is (claims per year) = 0.385*(age) + 5.218. If a customer is 44.315 years old and they make an average of 11.239 claims per year, the residual is -11.04. Interpret this residual in terms of the problem. Question 10 options: 1) The number of claims per year is 11.04 claims less than what we would expect. 2) The age is 11.04 years larger than what we would expect. 3) The age is 11.04 years less than what we would expect. 4) The number of claims per year is 11.239 claims less than what we would expect. 5) The number of claims per year is 11.04 claims…
