Answer to Question 1

1 - (0.16+ 0.05 + 0.01 ) + (1 - (0.09 + 0.15 + 0.16 ) - (0.14 + 0.17 + 0.16 + 0.07 ) = 0.84

Answer to Question 2

To find the IQR, we must obtain the 1st and 3rd quartiles. The 1st quartile Q1 is located in the 0.25(25 + 1 )th ordered position = 6.5th ordered position. Thus, Q1 = (669 + 672 )/2 = 670.50. The 3rd quartile is located in the 0.75(25 + 1 )th ordered position = 19.5th ordered position. Thus, Q3 = (705 + 706 )/2 = 705.5. Therefore IQR = 705.5 - 670.5 = 34.5.
