**Variance Estimation from Uniform Distribution**Consider drawing samples of size \( n = 12 \) from a uniform distribution \( U(0,12) \).### Estimators for the Population Variance- **Estimator \( s^2 \):** When you draw such a sample, what is \( E(s^2) \)? - *[Blank for student input]*- **Sample Range \( r \):** Another estimator is the sample range \( r \), where \( r = y_{\text{max}} - y_{\text{min}} \). When you draw such a sample, what is \( E(r) \)? - Hint: \( E(y_{\text{max}}) = \frac{144}{13} \) using Theorem 3.10.1. - *[Blank for student input]***Questions:**- Is \( r \) unbiased? - *[Blank for student input]* - Is \( r \) consistent? - *[Blank for student input]**Note: The highlighted areas are intended for answers or notes by the educator or student.*

Consider drawing samples of sizen = 12 from U(0,12) Consider estimators for the population variance. One such estimator is the familiar s'. When you draw such a sample, what is E(s') ? Another is the sample range r, where r = ymax - Ymin When you draw such a sample, what is E(r) ? Hint: E(y max) = 144/13 using Theorem 3.10.1
