Chapter B.1, Problem 9E

To determine

To calculate:

Score $\left(s\right)$ occurred with the greatest frequency and plot line plot.

Answer to Problem 9E

Line plot the quiz score is $15$ which occurred with a greatest frequency.

So the line plot is as below:

  

Explanation of Solution

Given information:

Quiz:

  $20,15,14,20,16,19,10,21,24,15,15,14,15,21,19,15,20,18,1,22,18,16,,18,19,21,19,16,20,14,12$

Exam:

  $77,100,77,70,83,89,87,85,81,84,81,78,79,78,88,85,90,92,75,81,85,100,98,81,,78,75,85,89,82,75$

Calculation:

Consider the quiz data which is provided in thebook tomake a line plot for the quiz scores of $30$ students.

According to the provided score of quiz the least score is $10$ and the greatest score is $24$ For plotting line plot, draw a portion of a real number line that includes the interval $\left[10,24\right]$ .

For creating the line plot starts with the least number $10$ to the higher number $24$ and then record a dot for each number.

So the line plot is as below:

  

So according to above line plot the quiz score is $15$ which occurred with a greatest frequency.
