Speed test. A police radar always overestimates the speed of incoming cars by an amount that is uniformly distributed between 0 and 10 km/hour. Assume that car speeds are uniformly distributed between 80 and 120 km/hour. If the radar's measurement for a car's speed is 124 km/hour, the LMS estimate of its speed is km/hour.

O The ratio of the variance accounted for by the observed values of Y to the variance accounted for by the predicted values of Y. O The MSR divided by the MS. O The SS, divided by the SSy.
Pulling Apart Wood. How heavy a load (in pounds) is 4step needed to pull apart pieces of Douglas fir 4 inches long and 1.5 inches square? Here are data from students doing a laboratory exercise: 33,190 31,860 32,590 26,520 33,280 32,320 33,020 32,030 30,460 32,700 23,040 30,930 32,720 33,650 32.340 24,050 30,170 31,300 28,730 31,920 We are willing to regard the wood pieces prepared for the lab session as an SRS of all similar pieces of Douglas fir. Engineers also commonly assume that characteristics of materials vary Normally. Suppose that the strength of pieces of wood like these follows a Normal distribution, with standard deviation 3000 pounds. Is there statistically significant evidence at thea = 0.10 level against the hypothesis that the meanis 32,500 pounds for the two-sided alternative? Is there statistically significant evidence at thea = 0.10 level against the hypothesis that the meanis 31,500 pounds for the two-sided alternative?
