You have a weekend job selecting speed limit signs to put at road curves. the speed limit is determined by the radius of the curve and the bank angle. part a for a turn of radius 410m and a 7.0? bank angle, what speed limit should you post so that a car traveling at that speed negotiates the turn successfully even when the road is wet and slick? v = ?

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?
