Answer :

To find the mean of the number of little birds Olivia sees in her yard each morning, we will follow these steps:

1. Collect the data:
- For Week 1: 31, 36, 24, 34, 45, 27, 41
- For Week 2: 16, 34, 29, 18, 25, 38, 31

2. Combine the data: Add the numbers from both weeks into a single list:
- 31, 36, 24, 34, 45, 27, 41, 16, 34, 29, 18, 25, 38, 31

3. Calculate the total: Add together all the counts of birds from the two weeks.
- Total sum = 31 + 36 + 24 + 34 + 45 + 27 + 41 + 16 + 34 + 29 + 18 + 25 + 38 + 31 = 429

4. Count the total number of days: There are 7 days in each week, and since she collected data for 2 weeks, we have:
- Total number of days = 7 + 7 = 14

5. Find the mean: Divide the total sum of the birds seen by the total number of days.
- Mean = 429 / 14 = 30.642857

6. Round the mean: Round the mean to the nearest whole number.
- Rounded mean = 31

Therefore, the mean number of little birds she sees each morning is approximately 31. The correct answer is option B.
