Question

if a person is making the maximum salary for a construction worker, they are making more than what percentage of teachers? they are making more than % of teachers. question help: video message instructor construction teacher salary (thousands of $) 20 25 30 35 40 45 50 55

Explanation:

Step1: Identify maximum construction salary

From the box - and - whisker plot, the maximum salary for construction workers is $50,000.

Step2: Count number of teachers above $50,000

In the teacher box - and - whisker plot, the number of data points (salaries) above $50,000 needs to be determined. Since the box - and - whisker plot represents the distribution of data, and we assume a normal distribution of teacher salaries for the purpose of percentage calculation. The upper whisker of the teacher plot ends around $55,000. We can estimate the percentage of teachers above $50,000. In a box - and - whisker plot, the box represents the middle 50% of the data (from Q1 to Q3), the lower whisker represents the lower 25% and the upper whisker represents the upper 25%. If we assume a somewhat symmetric distribution around the median, and we know that the upper quartile (Q3) for teachers is around $40,000. The upper whisker extends to $55,000. The percentage of data above $50,000 can be estimated by looking at the proportion of the upper whisker above $50,000. Since the upper whisker represents 25% of the data, and $50,000 is closer to the end of the upper whisker, we can estimate that about 10% of teachers have a salary higher than the maximum salary of construction workers.

Answer:

10%
