The following data shows the percentage of urban Indian households who have a high speed 5G internet connection:
| Year (\(x\)) | 2020 | 2021 | 2022 | 2023 | 2024 |
| Urban house hold (\(y\)) | 9% | 18% | 21% | 29% | 38% |
If a straight line trend by the method of least square for the above data is \(y = 23 + 6.9(x - 2022)\), then the forecast for the year 2025 is:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 43.7%
The trend equation is already given, so the forecast comes from putting x = 2025 into it:
\(y = 23 + 6.9(2025 - 2022)\)
\(= 23 + 6.9 \times 3\)
\(= 23 + 20.7 = 43.7\)
So the forecast for 2025 is 43.7%.
