On a 9-hole golf course the hole lengths are 150m, 300m, 250m, 325m, 275m, 350m, 225m, 400m, 425m. A golfer can learn to play only two strokes of different lengths which are played to exactly those lengths whenever played. If every stroke the golfer takes goes directly in line with the hole, what two lengths should the golfer learn in order to minimise the number of strokes needed to complete all 9 holes?

Analyze the data sets below. data set a 25,25,25,26,26,26,27,28,28,29,30,31,31,32,33,33,34,35,35,35 data set b 25,25,25,26,26,26,26,27,27,27,27,28,28,29,29,30,31,31,32,34 which of the following statement are true? select all that apply. a. data set a is relatively symmetric and data set b is skewed left. b.the means of the data sets are within 3 units from eachother. c.the data sets have the same standard deviation. d.the mean of data set a is 27.95 and the mean of data set b is 30. e. the data set b has a higher standard deviation than data set a. f. the mean and median of data set a are close in value.
