part a: bases on the imformation collected, who will have the higher mean annual salarypart b: if you were to graph this data what would be important to consider

In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data:
Table:
annual salaries (thousands of dollars)
Step 02:
higher mean annual salary:
College grad:
[tex]\operatorname{mean}\text{ =}\frac{41+67+53+48+45+60+59+55+52+52+50+59+44+49+52}{15}[/tex]mean = 52.4
High School grad:
[tex]\text{mean = }\frac{23+33+36+29+25+43+42+38+27+25+33+41+29+33+35}{15}[/tex]mean = 32.8
The answer is:
The College grad will have a higher mean annual salary.
