Answer :

To calculate the save percentage for each goalie and Pekka Rinne's single game stats, let's proceed step-by-step.

### Save Percentage Calculation for the Day's Top Goalies
The save percentage is calculated with the ratio of the number of saves to the total shots on goal. To convert this ratio to a percentage, we multiply it by 100.

#### 1. Roberto Luongo (Florida)
- Shots Against: 47
- Saves: 45
- Save Percentage (decimal): [tex]\( \frac{45}{47} = 0.9574468085106383 \)[/tex]
- Save Percentage (percent): [tex]\( 0.9574468085106383 \times 100 = 95.74468085106383\% \)[/tex]

#### 2. Darcy Kuemper (Arizona)
- Shots Against: 92
- Saves: 88
- Save Percentage (decimal): [tex]\( \frac{88}{92} = 0.9565217391304348 \)[/tex]
- Save Percentage (percent): [tex]\( 0.9565217391304348 \times 100 = 95.65217391304348\% \)[/tex]

#### 3. Jaroslav Halak (Boston)
- Shots Against: 230
- Saves: 219
- Save Percentage (decimal): [tex]\( \frac{219}{230} = 0.9521739130434783 \)[/tex]
- Save Percentage (percent): [tex]\( 0.9521739130434783 \times 100 = 95.21739130434783\% \)[/tex]

#### 4. Pekka Rinne (Nashville)
- Shots Against: 210
- Saves: 199
- Save Percentage (decimal): [tex]\( \frac{199}{210} = 0.9476190476190476 \)[/tex]
- Save Percentage (percent): [tex]\( 0.9476190476190476 \times 100 = 94.76190476190476\% \)[/tex]

Let's tabulate these results:

| Name | Team | Shots Against | Saves | Save Percentage (decimal) | Save Percentage (percent) |
|------------------|-----------|----------------|-------|--------------------------|---------------------------|
| Luongo, Roberto | Florida | 47 | 45 | 0.9574468085106383 | 95.74468085106383 |
| Kuemper, Darcy | Arizona | 92 | 88 | 0.9565217391304348 | 95.65217391304348 |
| Halak, Jaroslav | Boston | 230 | 219 | 0.9521739130434783 | 95.21739130434783 |
| Rinne, Pekka | Nashville | 210 | 199 | 0.9476190476190476 | 94.76190476190476 |

### Save Percentage for Pekka Rinne's Single Game
Let's move on to calculating the save percentage for a single game for Pekka Rinne. We will sum the saves and the shots against for each period, and then calculate the save percentage.

#### Period-wise Stats:
- 1st Period: 8 saves, 8 shots against
- 2nd Period: 8 saves, 9 shots against
- 3rd Period: 7 saves, 7 shots against

#### Calculation:
- Total Saves: [tex]\( 8 + 8 + 7 = 23 \)[/tex]
- Total Shots Against: [tex]\( 8 + 9 + 7 = 24 \)[/tex]
- Save Percentage (decimal): [tex]\( \frac{23}{24} = 0.9583333333333334 \)[/tex]
- Save Percentage (percent): [tex]\( 0.9583333333333334 \times 100 = 95.83333333333334\% \)[/tex]

Let's tabulate these results:

| Period | Saves | Shots Against |
|---------------|-------|---------------|
| 1st Period | 8 | 8 |
| 2nd Period | 8 | 9 |
| 3rd Period | 7 | 7 |
| Total | 23 | 24 |
| Save Percentage (decimal) | 0.9583333333333334 |
| Save Percentage (percent) | 95.83333333333334% |

With these calculations, we demonstrate the ability to determine save percentages both for multiple games over a season and for a single game, proving readiness for the role as a sports statistician.
