The number of orders returned due to a food issue (got the order wrong, food is cold, etc.) during the lunch rush at a fast food restaurant follows a Poisson distribution with a rate of 2.4 per hour.
a. What is the probability that one hour of the lunch rush has no orders returned?
b. The lunch rush lasts two hours. What is the probability that exactly six orders are returned during the lunch rush?
c. During a one-hour period of the lunch rush, eight orders were returned. Calculate the probability that eight or more orders are returned during a one-hour period. In what fraction of one-hour periods does this event occur? (give your answer in the form 1 out of every ______.)
What is the probability and Determine a 99% confidence interval estimate of the mean mileage.
The problem related to Statistics and it defines about calculation of average of students test score and representing it on a graph.
While dealing with 16 students, suppose that the alternative hypothesis has been one-sided and that it was set as Ha :
Supposing that both populations are normally distributed, construct a 99% confidence interval for the ratio of the two population variances.
Tthe United States during 1993 was $40,500. Assume the standard deviation was $8,500. Should a mobile home selling for $75,000 be considered an outlier? Explain why or why not.
First assume that at least one solution to the corresponding homogeneous equation is of the form . You may have to use some other method to find the second solution to make a fundamental set of solutions. Then use one of the two methods to find a ..
A machine is designed to produce gaskets with a mean inside diameter of 0.375 Inch. State the rejection region for the test statistic. Use an α = 0.01 level of significance. Suppose that a random sample of n = 20 gaskets had a mean of 0.373 inches. C..
Why might it not be a good idea to take the log of Hbath? Also generate a variable equal to the age of the house - how many valid observations do you have? Briefly explain why you will have exactly 6 fewer observations to use in estimating model
