Answer:

1.  [tex]Range = 24[/tex]

2.  [tex]Range = 98[/tex]

Step-by-step explanation:

Given

The data of quizzes

Required

Solving (a): Range of the 14 quizzes

[tex]Range = Highest - Least[/tex]

In this case;

[tex]Highest = 98[/tex]

[tex]Least = 74[/tex]

So;

[tex]Range = 98 - 74[/tex]

[tex]Range = 24[/tex]

Solving for (b): Range of 15 quizzes

In this case;

Least = 0

So; Range becomes

[tex]Range = 98 - 0[/tex]

[tex]Range = 98[/tex]
