Mrs. Clause wants to make a toy elf that can jump over a 1.5 m high wall. Beginning with the Law of Conservation of Energy, show her the work for each step to solve for the initial velocity that the toy elf needs to
have as it jumps off of the ground. Ignore the effects of air resistance. Show your equation, work and final
answer 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?
