Answer 1

Given

The boxplot.

And, the total number of students in the class is 60.

To find:

a) The percentage of students who received one or more moving violation.

b) The number of parking violations received by at least 50% of students.

c) How many students received two or more parking violation.

Step-by-step explanation:

a) From the figure,

The percentage of students who received one or more moving violation is,

`Percentage\text{ of students}=75\%`

Because the number of students having minimum moving violation is 0, and the number of students having maximum moving violation is 4.

b) The number of parking violation received by at least 50% of students is,

`\begin{gathered} Number\text{ }of\text{ }parking\text{ }violation\text{ received by at least 50}\%\text{ of students } \\ is\text{ }2\text{ }or\text{ }more. \end{gathered}`

c) The number of students who received two or more parking violation is,

`\begin{gathered} Number\text{ of students}=75\%*60 \\ =(75)/(100)*60 \\ =45 \end{gathered}`

Hence, the number of students who received two or more parking violation is 45.
