Answer 1

Answer:

Step-by-step explanation:

Given frequency table is,

                                                     Sport utility vehicle     Sports car    Row total

Speeding ticket within last year                 28                          35              63    

No Speeding ticket within last year           97                         104              201

Now relative frequency table will be,

                                                      Sport utility vehicle     Sports car    Row total

Speeding ticket within last year           $\frac{28}{63}=0.44$                 $\frac{35}{63}=0.56$         $\frac{63}{63}=1$  

No Speeding ticket within last year     $\frac{97}{201}=0.48$                $\frac{104}{201}=0.52$        $\frac{201}{201}=1$
