Answer:a

 a

    m  = 57.5

b

   \= x  = 50.14

Step-by-step explanation:

From the question we told that

  The stem plots for American League is

                  2\\3\ \ \ \ \ 5\\4 \ \ \ \ \ 0\  3 \ 9\\5 \ \ \ \ \ 1\ 4\ 7\ 8\ 8\\6 \ \ \ \ \ 4\ 8\ 8\\7 \ \ \ \ \ 5\ 7

Here the first column  is the tens while each digit in the in the second column is the unit of the first column

  For example row 3 means

      40 , 43, 49

The  sample  size is  n = 14  

Generally the median is mathematically represented as

         m  =  \frac{ K  +  Z}{2}

Here  K is the (\frac{n}{2}) th  \  term \ in \ the \  data \  given i.e  \frac{14}{2}  =  7th \  term

 From the stem plot the 7th term is  57

And

       K is the (\frac{n}{2} + 1) th  \  term \ in \ the \  data \  given i.e  \frac{14}{2} + 1 =  8th \  term

 From the stem plot the 8th term is  58

Thus the median is  

          m  =  \frac{ 57  +  58}{2}

=>       m  = 57.5

The stem plots for National League is

            2\ \ \  9\\3\ \ \ \ 1\\4 \ \ \ \ 2\ 6\ 7\ 8\ 8\\5 \ \ \ \  3\ 5\ 5\ 5\\6 \ \ \ \  3\ 3\ 7\\7\\

Generally the mean is mathematically evaluated as

           \= x  =  \frac{\sum x_i}{n}

           \= x  =  \frac{29 + 31 + 42 + 46 + 47 + 48 + 48 + 53 + 55+ 55+ 55+ 63+ 63+ 67}{14}

         \= x  = 50.14
