Perform test of hypothesis.1. DRIVING FOR PLEASURE. Two groups of drivers are surveyed to see how many milesper week they drive for pleasure trips. The data are shown. At alpha = 0.05 ( level ofsignificance), can it be concluded that single drivers do more driving for pleasuretrips on average than married drivers ?Single drivers :106110115121132 11997118122135110117116Married drivers:97104 13810211513312011913696139108117

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 Number of Driver Deaths per 100,000 64 32 55 30 72 36 34 30 31 18 16 29 21 22 32 18 46 24 46 31 Ho: ρ = 0Ha: ρ > 0 Find the Linear Correlation Coefficient r = Find the p-value p-value = The p-value is Greater than αα Less than (or equal to) αα The p-value leads to a decision to Do Not Reject Ho Reject Ho Accept Ho The conclusion is There is a significant linear correlation between driver age and number of driver deaths.
