You wish to determine if there is a negative 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 69 41 29 73 31 18 32 Ho: p = 0 Ha: p < 0 Find the Linear Correlation Coefficient r = Find the p-value p-value = The p-value is O Greater than a O Less than (or equal to) a 31 24 33 18 19 29 26 The p-value leads to a decision to O Accept Ho O Reject Ho O Do Not Reject Ho

You wish to determine if there is a linear correlation between the two variables at a significance level of a = 0.05. You have the following bivariate data set. Round to three decimal places. What is the critival value for this hypothesis test? = ± c.v. X y 27.7 -18.1 21.2 70.8 25.1 12.4 26.8 4.6 15.8 113.3 24.3 72.4 30.5 11.3 13.2 182.8 What is the correlation coefficient for this data set? r = Your final conclusion is that... There is sufficient sample evidence to support the claim that there is a statistically significant correlation between the two variables. There is insufficient sample evidence to support the claim the there is a correlation between the two variables.

At a .05 significance level with a sample size of 12, find the critical value for the correlation coefficient. (Just enter the positive value rounded to three places.)
