Question

During the early part of the 1994 baseball season, many sports fans and baseball players noticed that the number of home runs being hit seemed to be unusually large. Below are separate stemplots for the number of home runs by American League and National League teams based on the team-by-team statistics on home runs hit through Friday, June 3, 1994 (from the Columbus Dispatch, Sunday, June 5, 1994). Legend: 2|9 represents 29. What is the mean for the number of home runs for the National League teams

Answer 1

Complete Question

The picture of the stem plot National  and American League is shown on the first uploaded image

Answer:

The value is $\= x = 50.14$

Step-by-step explanation:

From the question we are told that

The stem plot for National League is

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

The  sample size is  n =  14

Generally the stem plot is interpreted in this manner

   The numbers on the first column represents the tens of a two digit number while the second column holds the possible unit number the tens in the first column can be combined with

  for example 4th row

 5           3 5 5 5

is equivalent to

53 55 55 55

Generally the mean for the national league is mathematically represented as

           $\= x = \frac{29 + 31 + \cdots + 67}{14}$

=>         $\= x = \frac{702}{14}$

=>         $\= x = 50.14$
