Lesson 2 Understand Unit Rate

Dawn earns $9.75 per hour while Amy earns $10 per hour.  

This information is important in comparing who is actually earning more than the other. Amy is earning $0.25 more than Dawn is earning. Thus, working for an extra 2 hours than Dawn made her earn $22.5 more than Dawn earned in a week.

Step-by-step explanation:

You can get the hourly work rate of Dawn and Amy by dividing their total earnings to the number of hours they worked.

You can get the difference in hourly rate by subtracting Dawn's earning from Amy's earning.

You can also get the difference in their weekly earnings by subtracting Dawn's total weekly earning from Amy's total weekly earning.

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
