Use the following information to answer the next ten questions. The data that follow are the square footage (in 1,000 feet squared) of 28 homes.
1.5 | 2.4 | 3.6 | 2.6 | 1.6 | 2.4 | 2.0 |
3.5 | 2.5 | 1.8 | 2.4 | 2.5 | 3.5 | 4.0 |
2.6 | 1.6 | 2.2 | 1.8 | 3.8 | 2.5 | 1.5 |
2.8 | 1.8 | 4.5 | 1.9 | 1.9 | 3.1 | 1.6 |
The sample mean = 2.50 and the sample standard deviation = 0.8302.
The distribution can be written as X ~ U(1.5, 4.5).
