Short Answer

Expert verified

The correct option is (c) It could be any number between $35,000 and $41,000

Step by step solution

01

Given Information

All-female workers earn an average of $35,000 a year.

The average male worker earns $41,000 per year.

02

Concept

The mean of a data set is determined by adding all of the numbers in the set and dividing by the number of values in the set. The median is the value in the middle of a data set when it is arranged from smallest to largest. The mode is the number that appears the most frequently in a data set.

03

Explanation

Because the mean of these two means will be in between these two means, the mean salary of all workers might be any figure between the means of females and males, which are $35,000 and $41,000, respectively.

How can we help wood surfaces resist weathering, especially when restoring historic wooden buildings? In a study of this question, researchers prepared wooden panels and then exposed them to the weather. Here are some of the variables recorded: type of wood (yellow poplar, pine, cedar); type of water repellent (solvent-based, water-based); paint thickness (millimeters); paint color (white, gray, light blue); weathering time (months).

Identify each variable as categorical or quantitative.

Cool car colors The most popular colors for cars and light trucks change over time. Silver passed green in 2000 to become the most popular color worldwide, then gave way to shades of white in 2007. Here is the distribution of colors for vehicles sold in North America in 2008
