Solution:
we are given that
Dukes science quiz scores are 99,91,60,94,and 95 .
we have been asked to describe the effect of the outlier on the mean and median.
Mean of the given data[tex] =\frac{99+91+60+94+95}{5} \\ [/tex]
Mean of the given data[tex] =\frac{439}{5}=87.8 \\ [/tex]
Median of the given data after arranging in the ascending order 60,91,94,95,99 is 94.
The outlier is 60.
The outlier is decreasing the value of Mean by [tex] 87.8-60=27.8\\ [/tex]
The outlier is decreasing the value of Median by [tex] 94-60=34\\ [/tex]
