i.
Draw histogram for given data.
i.
Answer to Problem 13.3MPS
Histogram for given data is
Explanation of Solution
Given:
Calculations:
Here, we have to draw histogram for given data.
Histogram is a vertical bar graph that shows grouped data. Only in histogram, there is no space between bars.
Conclusion:
Therefore, we are able to draw histogram for given data..
ii.
Calculate percent of students that earned more than $10 per hour.
ii.
Answer to Problem 13.3MPS
There are 56.25% of students who earned more than $10 per hour.
Explanation of Solution
Given:
Calculations:
Here, we have to calculate percentage of students that earned more than $10 per hour.
Total number of students are, (6+29+23+12+10) = 80.
According to table given, number of students that earned more than $10 are, (23+12+10) = 45
Thus, to calculate percentage of students that earned more than $10 per hour,
Conclusion:
Therefore, we are able to find the percent of students that earn more than $10 per hour.
iii.
State the hourly rate that contributes 15% of total data.
iii.
Answer to Problem 13.3MPS
Hourly rate of 12-13.99 $ will contributes 15% of total data.
Explanation of Solution
Given:
Calculations:
Here, we have to findhourly rate that contributes 15% of given data.
Total number of students are, (6+29+23+12+10) = 80.
Here, we have to find 15% of total students and their corresponding hourly rate.
From the given data, corresponding hourly rate for 12 students is 12-13.99$
Conclusion:
Therefore, we are able to find hourly rate of students that contributes 15% of given data.
