Sure, let's address both parts of the question in detail.
### Part A:
To find the formula Renee should put into cell C7, let's first understand what is desired.
Explanation:
- Cell C7 should contain the average of the values in cells B3 to B7.
- The required Excel formula to compute the average of values in a range is `=AVERAGE(range)`.
Solution:
Therefore, the formula Renee should put into cell C7 is:
```
=AVERAGE(B3:B7)
```
### Part B:
To calculate the 5-day Simple Moving Average (SMA) for eight consecutive days of closing prices, we’ll follow these steps:
Explanation:
- The 5-day SMA for a particular day is the average of the closing prices of the current day and the previous four days.
- Given closing prices for days 1 through 8, the 5-day SMA can only be computed starting from day 5.
We will manually compute the 5-day SMA for each relevant day:
1. For Day 5:
- Closing prices: [30.85, 31.15, 29.04, 31.10, 32.62]
- SMA = (30.85 + 31.15 + 29.04 + 31.10 + 32.62) / 5 = 30.952
2. For Day 6:
- Closing prices: [31.15, 29.04, 31.10, 32.62, 31.85]
- SMA = (31.15 + 29.04 + 31.10 + 32.62 + 31.85) / 5 = 31.152
3. For Day 7:
- Closing prices: [29.04, 31.10, 32.62, 31.85, 31.76]
- SMA = (29.04 + 31.10 + 32.62 + 31.85 + 31.76) / 5 = 31.274
4. For Day 8:
- Closing prices: [31.10, 32.62, 31.85, 31.76, 32.24]
- SMA = (31.10 + 32.62 + 31.85 + 31.76 + 32.24) / 5 = 31.914
Solution:
So, the 5-day SMA values for days 5 through 8 are as follows:
- Day 5: 30.952
- Day 6: 31.152
- Day 7: 31.274
- Day 8: 31.914
Summary:
- Part A: The formula to enter in cell C7 is `=AVERAGE(B3:B7)`.
- Part B: The 5-day SMA values for the given closing prices are approximately [30.952, 31.152, 31.274, 31.914], corresponding to days 5, 6, 7, and 8, respectively.
