When 20 employees were first hired in 2011 for an environmental engineering firm, Company A, the starting annual salary was $35,000. A competing environmental engineering firm, Company B, had the same starting salary for 20 employees hired the same year. In 2016, data was collected on the annual salaries of the same employees at each company. This data is displayed in the box plot shown. Part A: Compare the annual salary distributions. Part B: What are the pros and cons of working at each company? Explain using what you found in Part A.

Part A :- 1) Company A 's miminum value is less than that of Company B' . 2) Company A 's maximum value is greater than that of Company B's .

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.
