Answer:

The correct option is  C

Step-by-step explanation:

The  sample  

                                                                                          Household Income

                                                                                     < $60,000    > $60,000

I would never purchase a newspaper subscription.          40                63

I might or might not purchase a newspaper subscription. 53                70

I would probably purchase a newspaper subscription.     65                 32

I already purchase a newspaper subscription.                   73                 16

Generally the sample size is mathematically represented as

       $n = 40 + 53 + 65+ 73 + 63 + 70 + 32+ 16$

=>    $n = 412$

Generally the number of the sample with an income greater $60,000 is mathematically represented as

        $N = 63 + 70 + 32 + 16$

=>     $N = 181$

Generally the number of  families with an income more than $60,000 who might or might not purchase a newspaper subscription is

      $X = 70$

Generally the percentage of families with an income more than $60,000 who might or might not purchase a newspaper subscription is

           $P(X) = \frac{70}{181} * 100$

=>        $P(X) = 39\%$
