Chapter B.1, Problem 10E

To determine

To calculate:

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

Answer to Problem 10E

Line plot the exam score is $81$ and $85$ 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 exam data which is provided in the book to make a line plot for the quiz scores of $30$ students.

According to the provided score of exam the least score is $70$ and the greatest score is $100$ For plotting line plot, draw a portion of a real number line that includes the interval $\left[70,100\right]$ .

For creating the line plot starts with the least number $70$ to the higher number $100$ and then record a dot for each number.

So the line plot is as below:

  

So according to above line plot the exam score is $81$ and $85$ which occurred with a equal greatest frequency.
