Question

9.2.8
Supercavitation is a propulsion technology for undersea vehicles that can greatly increase their speed. It occurs above approximately 50 meters per second, when the
pressure drops off sufficiently to allow the water to dissociate into water vapor forming a gas bubble behind the vehicle. When the gas bubble completely encloses the
vehicle, supercavitation is said to occur. Eight (n = 8) tests were conducted on a scale model of an undersea vehicle in a towing basin with the average observed speed
I = 102.2 meters per second. Assume that speed is normally distributed with o = 4 meters per second. Use a = 0.05.
(a) Test Ho : µ = 100 versus Hj : u < 100.
(b) Compute the power of this test if the true mean speed is low as 95 meters per second. Round your answer to four decimal places (e.g. 98.7654).
(c) What sample size would be required if we want to detect a true mean speed as low as 96 meters per second if we wanted the power of the test to be at least 0.85.

MacBurger's is attempting to determine how many servers (or lines) should be available during the breakfast shift. During each hour, an average of 100 customers arrive at the restaurant. Each line or server can handle an average of 50 customers per hour. A server costs $5 per hour, and the cost of a customer waiting in line for 1 hour is $20. Assuming that an M/M/s/GD/infinity/infinity model is applicable, determine the number of lines that minimizes the sum of delay and service costs. please explain step by step.
Tank B, a 30-litre tank, initially contains 6 grams of salt in 15 litres of water. At t = 0, saltwater with a concentration of 1 gram of salt per litre is poured from Tank A into Tank B at a rate of 2 litres per minute, while the well mixed solution leaves the bottom of Tank B at a rate of one litre per minute. a) derive the IVP that models the rate of change of the quantity of salt in Tank B with respect to time,b) solve the IVP, andc) determine the quantity and concentration of salt in Tank B at the instant Tank B is full
