(another tomato/skyscraper problem.) you are looking out your window in a skyscraper, and again your window is at a height of 450 feet above the ground. this time, however, you know that the tomato was dropped (so v0 = 0), but you did not see it dropped so you do not know when it was dropped. you measure that it takes exactly 2 seconds from the time the tomato passes your window until it hits the ground. from what height did it fall? give your answer as a decimal approximation with units.

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
