#1. An LED launches 180$\mu$W of power into the end of a fiber. a. How much power would emerge at the end of the fiber at a distance of 500m if the fiber were specified as having a loss of 0.2dB/km. b. What would the loss of the fiber be in decibels per kilometer if 172$\mu$W were measured at the output of the fiber 500m away?

Question 5 What is the importance of adding Sulfuric acid to the sample (analyte) prior to starting the titation? Sulfuric Acid provides the H+ to replace the Na in the NaC2O4. Sulfuric Acid allows the indicator to work properly. Sulfuric acid is not needed in the redox titration for any specific reason. Without Sulfuric Acid the chemicals used would need to be more concentrated. 2 pts

7. Consider the estimated linear regression model: $Y_i = \hat{\beta}_0 + \hat{\beta}_1 X_i + \hat{u}_i$, A. Write the expressions for the least squares estimators of the intercept and slope coefficients. B. Suppose that instead of the dependent variable Y, you estimate a model where the variable Z is the dependent variable. The estimated model is given by: $Z_i = \hat{\beta}^*_0 + \hat{\beta}^*_1 X_i + \hat{u}^*_i$, where * distinguishes the estimates from those in (A). Write the expressions for the least squares estimators of the intercept and slope coefficients. C. Next, suppose the variable Z is a linear function of Y. Specifically, let $Z_i = aY_i$, where a is a constant. Considering your results from A and B, show how: i) $\hat{\beta}_1$ and $\hat{\beta}^*_1$ are related in terms of the constant a ii) $\hat{\beta}_0$ and $\hat{\beta}^*_0$ are related in terms of the constant a
