Some calculated statistics for the data are also shown here: mean 294,822 min- 258,680 Q-276,055 med - 295,000 Qu-299,000 max - 328,209 Cal Poly's president Baker earned $328,209. Use the outlier test to determine if his salary is an outlier. std. dev.-17,669 268,000 2700002 270,000 280,000 290,000 300,000 310,000 20,000 0,000 Salary Gn dollars) no, since his salary is below $329,417.5, it is NOT an outlier O yes, since his salary is the maximum, it is an outlier O yes, since his salary is above $312,491, it is an outlier O no, since his salary is below $333,4175, it is NOT an outlier

Explanation / Answer

Result:

Range = 328209-258680 = 69529

IQR = 299000-276055 =22945

Maximum outlier limit = Qu+1.5*IQR

= 299000+1.5*22945

=333417.5

No, since his salary is below $333417.5, it is not an outlier.
