Answer 1

Construct the dotplot for the age of the players of the New England Patriots in 2012 by using MINITAB, which is shown in figure below.

 

MINITAB Procedure:

Step 1: Choose Graph > Dotplot.

Step 2: Choose One Y-Simple and then click OK.

Step 3: In Graph variables, enter “Age”.

Step 4: Click OK.

 

MINITAB output:

 

Observation:

From above figure, the right side of the dotplot is extended larger than the left side. Hence, the distribution of the dotplot seems to be positively skewed. Majority of the players fall between 21 and 30 years old. Also, from the dotplot, there is a peak at age 24 with 7 players and age 25 with 8 players.
