Question

What is the five-number summary for the data set?

Answer 1

The correct answer is:  [D]:
_____________________________________________________
    " Minimum: 21, Q₁: 27.5, Q₂: 42, Q₃: 53.5, Maximum: 70 " .
_________________________________________________________
   Note:  Rearrange the numbers in the data set from least to greatest:
_________________________________________________________
                   {21, 23, 32, 39, 42, 43, 48, 59, 70} .
_________________________________________________________
Since there are an odd number of values in the data set, 
_________________________________________________________
   "Q₁ = (23+32)/2 = 55/2 = 27.5 " ;

   "Q₃ = (48 + 59) /2 =  107 = 53.5 " ;
_____________________________________________________
         The minimum (lowest value) is "21" (as we can see); and the maximum (highest value) is "70" (as we can see).
_____________________________________________________
  These values correspond to:  "Answer choice:  [D]: 
_____________________________________________________
   " Minimum: 21, Q₁: 27.5, Q₂: 42, Q₃: 53.5, Maximum: 70 " .
