Answer 1

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
