590 815 575 608 350 1285 408 540 555 679
a. Calculate and interpret the sample mean and median.
b. Suppose the 6th observation had been 985 rather than
1285. How would the mean and median change?
c. Calculate a 20% trimmed mean by first trimming the two
smallest and two largest observations.
d. Calculate a 15% trimmed mean.

Best ResponseYou've already chosen the best response.0a. To calculate the sample mean, add the 10 amounts and divide the total by 10. To find the median, rank the amounts in ascending order (lowest amount first). Since there is an even number of data the median is found by taking the arithmetic mean of the fifth and sixth amounts.
