The document discusses calculating statistics for a sample data set. It asks the reader to (1) calculate the sample mean and median, explaining why they differ due to skewness in the data, (2) determine the 10% trimmed mean and compare it to the mean and median, (3) determine by how much the lowest observation could be increased without changing the sample median.

1. (a) Determine the values of the sarriple mean and sample median. [ Hint: x y = 18.59 . ] (Rourid
your ariswers to four decimal places.) x = 1.2593 x = 1.57 Explain why they are different. There
is heavy nepative skewness in the date. They aren't different sines the data is symmetric. There is
heavy positive skewness in the deta. There are an odd number of data values. The sample mean
and sample mediar are never equal. (b) Determine the value of the 10% trimmed mean. (Round
your answer to four decimal places.) Compare to the mean and median. It is above bath the meen
and the median. It is between the values of the mean and median. It is the same as the median. It
is belaw both the mean and median. It is the same as the mean. (c) By how much could the
observation 0.20 be increased without impacting the value of the sample median?
