Probability and Statistical Inference 9
Let \(m\) denote the median weight of 80-pound bags of water softener pellets. Use the following random sample of \(n=14\) weights to find an approximate 95% confidence interval for \(m\): \(\begin{array}{lllllll} 80.51 & 80.28 & 80.40 & 80.35 & 80.38 & 80.28 & 80.27 \\ 80.16 & 80.59 & 80.56 & 80.32

A football quarterback is moving straight backward at a speed of 2.00 m/s when he throws a pass to a player 18.0 m straight downfield. (a) If the ball is thrown at an angle of 25 relative to the ground and is caught at the same height as it is released, what is its initial speed relative to the groun

Write down the Lagrangian for a projectile (subject to no air resistance) in terms of its Cartesian coordinates (x, y, z), with z measured vertically upward. Find the three Lagrange equations and show that they are exactly what you would expect for the equations of motion.

Biology 8
Herbivory (plant-eating) has evolved repeatedly in insects, typically from meat-eating or detritus-feeding ancestors (detritus is dead organic matter). Moths and butterflies, for example, eat plants. whereas their "sister group" (the insect group to which they are most closely related), the caddisfli
