The production manager at Bellevue Steel, a manufacturer of wheelchairs, wants to perform a second analysis of the number of defective wheelchairs produced on the day shift and afternoon shift.
The quality control department of Widgets Manufacturing needs your help. They can't decide which significance level is appropriate for testing the claim that fewer than 50% of widgets from a production run are defective.
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. (Accommodating 100% of males would require very wide seats that would be too expensive.)
Soft Drinks a vending machine automatically pours soft drinks into cups. As the amount of soft drink dispensed into a cup is normally distributed
Find a 95% confidence interval for the mean price of all summer sleeping bags.
New soft drink is being market tested. A sample of 400 individuals participated in the taste test and 100 indicated that they like the taste. Set up the null and the alternative hypotheses.
Find the probability that a man and woman are watching the schow at the same time. (This question confused me because it sounds like the statement I just wrote before this one)
Describe expected value (EV) of an investment if there is a 20% chance of realizing a return of $20,000 or a 55% chance of realizing a return of $25,000, or there could be a loss of $15,000?
Suppose a company owns three cars that get 20 miles per gallon, two cars that get 22 miles per gallon and one car that gets 24 miles per gallon. Would the mean miles per gallon be 22?
In a test of the independence of two variables, one of the variables has two possible categories and the other has three possible categories.
Obvious tests In many cases, hypothesis testing is used when the evidence is obvious. For example, why would you even bother testing if the true mean is 50 ppm?
Using the .10 level of significance, can we conclude that the assembly time using the new method is faster?
