A magazine tested paints. The table below shows the overall quality score and cost in dollars per gallon. Use the rank correlation coefficient to test for a correlation between the two variables. Use a significance level of a = 0.05. Based on these results, do you get better quality paint by paying more?

You wish to determine if there is a linear correlation between the age of a driver and the number of driver deaths. The following table represents the age of a driver and the number of driver deaths per 100,000. Use a significance level of 0.01 and round all values to 4 decimal places. Driver Age Number of Driver Deaths per 100,000 65 27 34 27 76 24 55 34 71 21 49 24 34 36 27 19   Ho: ρ = 0Ha: ρ ≠ 0 Find the Linear Correlation Coefficient    r =  Find the p-value   p-value =    The p-value is Less than (or equal to) αα Greater than αα   The p-value leads to a decision to Reject Ho Accept Ho Do Not Reject Ho   The conclusion is  There is a significant positive linear correlation between driver age and number of driver deaths. There is a significant linear correlation between driver age and number of driver deaths. There is a significant negative linear correlation between driver age and number of driver deaths. There is insufficient evidence to make a…

UnattemptedQuestion 1Expand PreviousNext   The data below was collected from manufacturer advertisements of their vehicles' horsepower and highway gas mileage (mpg.). Use this data to answer the following questions. x 158 250 340 350 390 190 220 y 33 28 15 17 11 35 42 1. Find the p-value to determine if there is a linear correlation between horsepower and highway gas mileage (mpg).  If there is a linear correlation, write the correlation coefficient below if there is a linear correlation, write the regression equation below.  Using the data shown above, predict the the highway gas mileage (mpg) for a car that has a horsepower of 225 If there is a linear correlation, what percentage of variation in highway gas mileage (mpg) can be explained by horsepower?
