In a carnival game, a ball is thrown at a plank hanging vertically downwards from a hinge such that it is free to rotate after the ball strikes it. The ball has a mass of 0.5 𝑘𝑘𝑘𝑘 and meets the plank with a horizontal velocity of 6 𝑚𝑚/𝑠𝑠; it strikes the plank, which has mass 8 kg, at the very bottom of the plank - a distance 1.5 𝑚𝑚 from its hinge point. The coefficient of restitution of this collision is 𝑒𝑒 = 0.6. If the impact takes 1 𝑚𝑚𝑠𝑠, find (a) the final velocity of the ball, (b) the angular velocity of the plank, and (c) the average force imparted on the ball during this collision

Two substance abuse clinics would like to compare retention rates for the programs offered by each to see whether the proportion of clients who stayed in after days is different for the two clinics. A simple random sample of clients from each clinic is taken, recording whether the client was still in the program after days. Clinic B has more clients and was able to collect a larger sample. The results of the sample are shown below.What is the level of significance?The null hypothesis is The alternative hypothesis Should be rejected or does fail to be rejected?What conclusion can be drawn from the data?What are the population parameters?evidence exists to support the claim that retention rates for the two clinics are different.
