Answer to Question 1

(0.11 + 0.11 )/(0.15 + 0.11 + 0.11 ) = 0.22/0.37 = 0.595

Answer to Question 2

Not possible. There must be two 87s in order to have a mode of 87, and there can only be two data values larger than 70 in order for 70 to be the median, which is impossible since 100 is one of the numbers, and that makes three of the five numbers larger than 70.
