Question

A Basketball Coach closely watches the shots of 60 players during basketball try-outs. Complete the two-way frequency table to show her observations.

Hint:

  • Categories are labelled in the left column and top row.
  • The counts are placed in the centre of the table.
  • Totals appear at the end of each row and column.
  • A sum of all counts (a grand total) is placed at the bottom right.

The correct answer is: 28,32,60


    Answer:
    • Step by step explanation: 
      • Given:


    Yes

    No

    Total

    Underclassmen

    18

    a

    28

    Upperclassmen

    b

    19

    c

    Total

    31

    d

    e

    • Step 1:
    Find a.
    As, we know,
    Totals appear at the end of each row and column

    thereforea + 18 = 28

    a = 28 – 18

    a = 10

    • Step 2:
    Find b.
    As, we know,
    Totals appear at the end of each row and column

    therefore18 + b = 31

    b = 31 - 18

    b = 13

    • Step 3:
    Find c.
    As, we know,
    Totals appear at the end of each row and column

    thereforeb + 19 = c

    c = 13 + 19

    c = 32

    • Step 4:
    Find d
    As, we know,
    Totals appear at the end of each row and column

    thereforea + 19 = d

    d = 10 + 19

    d = 29

    • Step 5:
    Find e.
    As, we know,
    A sum of all counts (a grand total) is placed at the bottom right

    therefore28 + c = e

    e = 32 + 28

    e = 60
