To find the mean of each row of the population data, we first need to organize the data into how Nadya placed it in the table. The data you provided seems to be a single list of numbers, so we will consider four rows with four entries each.
Based on the data provided, here's how it might typically be structured:
- Row 1: 2, 4, 5, 4
- Row 2: 5, 2, 4, 2
- Row 3: 4, 3, 4, 3
- Row 4: 2, 4, 4, 3
Now, we will calculate the mean for each of the rows:
Row 1:
Numbers = 2, 4, 5, 4
Mean = (2 + 4 + 5 + 4) / 4 = 15 / 4 = 3.75
Row 2:
Numbers = 5, 2, 4, 2
Mean = (5 + 2 + 4 + 2) / 4 = 13 / 4 = 3.25
Row 3:
Numbers = 4, 3, 4, 3
Mean = (4 + 3 + 4 + 3) / 4 = 14 / 4 = 3.5
Row 4:
Numbers = 2, 4, 4, 3
Mean = (2 + 4 + 4 + 3) / 4 = 13 / 4 = 3.25
Now we have the means of each row:
- Row 1 Mean: 3.75
- Row 2 Mean: 3.25
- Row 3 Mean: 3.5
- Row 4 Mean: 3.25
The means range from 3.25 to 3.75.
To find the interval within which the mean of the actual population might fall, we can look at the minimum and maximum of the means calculated. The overall range of the means is:
- Minimum mean = 3.25
- Maximum mean = 3.75
Thus, the mean of the actual population will be found between 3.25 and 3.75.
Based on the given answer choices, the most appropriate interval is 3.2 and 4.
Conclusively, the mean of the actual population will be found between values 3.2 and 4.
