Section 05.02 Exercise 30 - Find the confidence interval The concentration of carbon monoxide (CO) in a gas sample is measured by a spectrophotometer and found to be 85 ppm. Through long experience with this instrument, it is believed that its measurements are unbiased and normally distributed, with an uncertainty (standard deviation) of 11.00 ppm. Find a 95% confidence interval for the concentration of CO in this sample. (Round the final answer to three decimal places.) The 95% confidence interval is (_____________, ______________).

Suppose you have the following regression model: $Y = \beta_0 + \beta_1 X_1 + e$ You estimate this model, but later find that there is an omitted variable $X_2$, which is correlated with both $X_1$ and $Y$. The true model is: $Y = \beta_0 + \beta_1 X_1 + \beta_2 X_2 + e$ The omitted variable $X_2$ is correlated with $X_1$ such that $X_1 = \alpha + \rho X_2 + \nu$ If $\beta_2 > 0$ and $\rho < 0$, what effect does omitting $X_2$ have on the estimate of $\beta_1$? will be unbiased. will remain the same. will be too low. will be too high.

Express the definite integral as an infinite series in the form \sum_{n=0}^{\infty} a_n. $\int_0^1 3 \tan^{-1} (x^2) dx$ (Express numbers in exact form. Use symbolic notation and fractions where needed.) $a_n = \frac{(-1)^n (3)}{(2n+1)(4n+3)}$ Find the value of this integral to within an error of at most $10^{-5}$. (Use decimal notation. Give your answer to five decimal places.) $\int_0^1 3 \tan^{-1} (x^2) dx \approx 0.89313$ Incorrect
