Sort the following quantities as known, to find, or unneeded. Let m and v be the mass and speed of the car, respectively; μs is the coefficient of static friction, r is the radius of the circular path, n is the magnitude of the normal force acting on the car, and ΣFx is the x component of the net force acting on the car. Use the information you collected in the Prepare step to find the net force on the car.

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?
