John Rengel is the Quality Assurance Supervisor for Vino Supremo Vinyards. He knows that 10 percent of each box of corks is undersized.
a) If he were to randomly select 120 corks from the next box, then how many of these corks would John expect to be undersized?b) If he were to randomly select 120 corks from each box, then what would John calculate as the standard error of the number of undersized corks?c) What is the probability that John will find 15 or more corks defective in a randomly selected box?
From the given polynomials, identify the polynomials of degree one. I know that I have to use the substitution methode and the elimination. I am not sure if I applied the correct system.
A random sample of n=9 men between 30-39 years old is asked to do as many sit ups as they can in one minute. The mean number is x=26.2 and the standard deviation is s=6. Find a 95% confidence interval for the population mean.

In the graphical method, how do you know when a problem is infeasible, unbounded, or when it has multiple optimal solutions? What are the essential ingredients of an LP model? Why is it helpful to understand the characteristics of LP models?
The amount ($1.00, $5.00, $10.00, $25.00, or $50.00) promised to each person was determined by randomization. For each person who was sent one of the surveys, The value of the X2 test statistic for testing the hypothesis
Suppose it is desired to estimate the population mean number of miles with a margin of error of ± 2 miles at 95% confidence. Do the data provide this desired level of precision? What action, if any, would you recommend be taken?
An experiment was performed to investigate lifetime of a component exposed to high heat. Three different oven types were used at either 550°F or 600°F.
Give an example of a null and alternative hypotheses. This can be a personal item or something at work. Additionally, identify the Type I and Type II Errors that could occur with your decision-making process.
