Answer:
a. mean=$489,414.80
median=$265,664
b. Meidan. Not affected by outlier values.
Step-by-step explanation:
#Mean is calculated using the the formula:

Hence, the mean winning is $489,414.80
#Our data points are even.
-We first arrange the data points in increasing order.
-The median is calculated as the average of the two middlemost data points.
Hence, the median point is $265,664
The Median is the best measure of central limit theorem as it's not affected by extreme outlier values.
-We have one outlier value of $2,194,246 which shifted the mean from $299,989.11 to $489,414.80
