In the setup below, a mass is hung from a string (𝜇 = 0.002 kg/m) that passes over a light pulley. The string is connected to an oscillator of frequency f. The string has a length of 𝐿 = 2.0 m. When the hanging mass is 𝑀 = 16 kg or 25 kg, standing waves are observed. No standing waves are observed with any intermediate mass. a) What is the frequency of the oscillations? b) What is the largest mass for which standing waves could be observed?

The Inn at Penn hotel has 110 rooms with standard queen-size beds and two rates: a full price of $170 and a discount price of $100. To receive the discount price, a customer must purchase the room at least two weeks in advance (this helps to distinguish between leisure travelers, who tend to book early, and business travelers, who value the flexibility of booking late). For a particular Tuesday night, the hotel estimates that the demand from leisure travelers could fill the whole hotel while the demand from business travelers is distributed normally with a mean of 80 rooms and a standard deviation of 20. Find the optimal protection level for full-price rooms (the number of rooms to be protected from sale at a discount price).

Can someone please help me? I don't understand how to do it. 2-(15 points) Compute a 95% Confidence Interval for the Difference in Population Proportions based on the following data summary. Then test Ho: p1 - p2 = 0 vs HA: p1 - p2 ≠0 at α = 0.05. Population 1: p1 = 0.78, n1 = 200 Population 2: p2 = 0.85, n2 = 250 Sample Proportion: P Sample Size: n
