Measles and Mumps The data show the number of cases of measles and mumps for a recent 5-year period. Measles Cases 41 142 71 61 202 Mumps Cases 817 462 1983 2605 354 Send data to Excel The correlation coefficient for the data is r=-0.647 and a= 0.05. Should regression analysis be done? The regression analysis should not be done. O The regression analysis should be done. Find the equation of the regression line. Round the coefficients to at least three decimal places. y a+bx a = b = Given a year with 164 cases of measles, predict the expected number of cases of mumps for that year. Round y answer to at least one decimal place. The number of cases of mumps for that year is

Prices and mileage of 48 Dodge 2500 Pickup trucks with Cummins diesel engines.  Prices ranged from $28,925 to $68,650.  Mileage ranged from 315 to 186,466.   While I did not share the trucks were 2013 to 2020 models. Please show all work.  Interpret b0 in the context of this problem.  Interpret b1 in the context of this problem.  What percent of total variation in prices is explained by the regression model?  Provide evidence to support your answer.

Use the value of the linear correlation coefficient to calculate the coefficient of determination. What does this tell you about the explained variation of the data about the regression​ line? About the unexplained​ variation?

EQuestion Help Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line. (The pair of variables have a significant correlation) Then use the regression equation to predict the value of y for each of the given x-values, if meaningful.
