Question

Five starting basketball players were randomly selected from two teams. The heights, in inches, of five players on Team I are 72, 73, 76, 76, and 78; the heights of those on Team II are 67, 72, 76,76, and 84" (please use the correct symbols in your answers, for example, x : # or μ4. ) 2. (1) Find the mean, median, mode and range of each team, respectively. (2) Are the four numbers you found in (1) statistics or parameters? (3) Calculate the standard deviation of each team, respectively. (please show detailed calculation work for this question, you can use graphing calculator or other software to check your final answer) (4) Based on the standard deviations you found in (2), which team players' heights have a larger variation?

Answer 1

1)

	team 1	team 2
	72	67
	73	72
	76	76
	76	76
	78	84
mean	75	75
median	76	76
mode	76	76
range	6	17

2)

these are statistic as they are summary for sample

3)

team 1 , sd = 2.449

team 2 sd = 6.245

4)

team 2 player have more variation as their sd is more
