I need the graph by grouping

2. Nicholas is interested in determining whether amount of training influences how many goals hockey players score during a hockey season. To test this, Nicholas recruits a sample of 20 hockey players. Half of these hockey players have received only a small amount of training; the other half have received a large amount of training. Nicholas then records how many goals each of these hockey players scores during a hockey season. The data follows. Small amount of training Large amount of training 2 16 0 4 1 14 6 12 7 9 5 22 7 14 3 18 00 17 6 25 a) Is this study an experiment or an observational study? (1 point) b) What is Nicholas' population? (1 point) c) What is Nicholas' sample? (1 point) d) What is the independent variable? If there aren't any, write N/A. (1 point) e) What is(are) the dependent variable(s)? If there aren't any, write N/A. (1 point) f) If there is an independent variable, on what scale is it measured? If there aren't any, write N/A. (1 point) g) If there is(are) dependent variable(s), on what scale is(are) it(they) measured? If there aren't any, write N/A. (1 point) h) Display the "goals scored" variable data, for the "large amount of training" group only, using a frequency distribution table. (3 points) ) Display the "goals scored" variable data, for the "large amount of training" group only, using a frequency distribution graph. (4 points) j) What is the shape of the graph created in i)? (1 point) k) Calculate the most appropriate measure of central tendency for the "goals scored" variable data, for the "large amount of training" group only, and don't forget to state which measure you're calculating. (2 points) ) Calculate the standard deviation of the "goals scored" variable data, for the "large amount of training" group only. (3 points) m) For the "goals scored" variable data, for the "large amount of training" group only, transform X = 12 into a z-score. (1 point) n) Where is the z-score that you calculated in part m), with respect to the middle of the sample's distribution? (1 point)2.
