Plus Minus 1 - Method of Moments 3 points possible (graded) Let \( X \) be a random variable that takes on values -1 and +1 with probabilities \( p \) and \( 1-p \), respectively. Let \( \widehat{m}_{1} \) be the sample average of \( n \) i.i.d. observations of \( X \). What is the method of moments estimator \( \hat{p}_{n}^{\mathrm{MM}} \) ? Use hatm_1 for \( \widehat{m}_{1} \). Assume that we observe \( k \) instances of -1 out of \( n \) outcomes. What is the ML estimator \( \hat{p}_{n}^{\mathrm{MLE}} \) ? Are the two estimators for the \( \pm 1 \) random variable equal? Yes No

Two fire-lookout stations are 18 miles apart, with station B directly east of station A. Both stations spot a fire. The bearing of the fire from station A is N35°E and the bearing of the fire from station B is N30°W. How far, to the nearest tenth of a mile, is the fire from each lookout station? The distance from station B to the fire is miles. (Do not round until the final answer. Then round to the nearest tenth as needed.)
