High airline occupancy rates on scheduled flights are essential for profitability. Suppose that a scheduled flight must average at least 60% occupancy to be profitable and that an examination of the occupancy rates for 120 10:00 A.M. flights from Atlanta to Dallas showed mean occupancy rate per flight of 58% and standard deviation 11%. Test to see if sufficient evidence exists to support a claim that the flight is unprofitable. Find the p-value associated with the test. What would you conclude if you wished to implement the test at the

$$\alpha = .10$$

A completely filled barrel and its contents have a combined mass of $90 \mathrm{~kg}$ and a center of mass at $G$. A cylinder $C$ with a mass of $200 \mathrm{~kg}$ is connected to the barrel as shown. Knowing $\mu_s=0.40$ and $\mu_k=0.35$, determine the maximum height $h$ so the barrel will not tip.

In this exercises, find the reference angle for each angle.
