To fill in the totals in the two-way table, you need to add the values in each row and column, and then fill in the overall total for the entire table.

Given data:

  • Cold, Cloudy: 40
  • Cold, Sunny: 5
  • Warm, Cloudy: 10
  • Warm, Sunny: 35

Step 1: Calculate the row totals.

For the Cold row:

  • Total for Cold = Cloudy + Sunny = 40 + 5 = 45

For the Warm row:

  • Total for Warm = Cloudy + Sunny = 10 + 35 = 45

Step 2: Calculate the column totals.

For the Cloudy column:

  • Total for Cloudy = Cold + Warm = 40 + 10 = 50

For the Sunny column:

  • Total for Sunny = Cold + Warm = 5 + 35 = 40

Step 3: Calculate the grand total.

The grand total is simply the sum of all the individual counts:

  • Total for all days = Total Cold + Total Warm = 45 + 45 = 90

Completed table:

Now, filling in the table:

                Cloudy   Sunny   Totals
Cold            40       5       45
Warm            10       35      45
Totals          50       40      90

So the filled in totals in the two-way table are:

  • Totals for Cold = 45
  • Totals for Warm = 45
  • Total for Cloudy = 50
  • Total for Sunny = 40
  • Grand Total = 90
