An air-standard Diesel cycle has a compression ratio of 18.2. Air is at 80°F and 14.7 psia at the beginning of the compression process and at 3000 R at the end of the heat addition process. Accounting for the variation of specific heats with temperature, determine
(a) The cutoff ratio,
(b) The heat rejection per unit mass, and
(c) The thermal efficiency.
Problem 1: Use the definition of an improper integral to evaluate the integral below:
The mean incubation time of fertilized chicken eggs keep at 100.5oF in a still-air incubator is 21 days. Suppose that the incubation times are approximately normally distributed with standard deviation of 1 day. If you are taking 400 random sample..

Question 1: When comparing two population means with an unknown standard deviation you use a t test and you use N-2 degrees of freedom.
Find the mean and standard deviation of the number who spend at least $15 per month. What is the probability that at least 40% of them will spend a t least $15 per month?
The 100% rule is used in decision modeling to determine whether or not a change in project constraints or variables will affect the outcome of a decision. Under the 100% rule, any combination changes can occur without a change in the solution, as ..
