Question

You wish to determine if there is a positive 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 0.05 and round all values to 4 decimal places. Driver Age 18 65 72 33 74 66 51 Number of Driver Deaths per 100,000 25 32 21 33 19 18 23 Ho: p = 0 Ha: p > 0 Find the Linear Correlation Coefficient re Find the p-value p-value The p-value is O Greater than a Less than (or equal to) a The p-value leads to a decision to O Reject Ho O Do Not Reject Ho Accept Ho
