There is a proctoru final exam for the last week of class

Solve the problem.How many tissues should a package of tissues contain? Researchers have determined that a person uses an average of 66 tissues during a cold. Suppose a random sample of 2500 people yielded the following data on the number of tissues used during a cold: We want to test the alternative hypothesis Ha: μ < 66. State the correct rejection region for

Solve the problem.Data were collected from the sale of 25 properties by a local real estate agent. The following printout concentrated on the land value variable from the sampled properties. HYPOTHESIS: MEAN X = x What is the correct conclusion when testing a greater-than alternative hypothesis at α = .05?

Solve the problem.A consumer product magazine recently ran a story concerning the increasing prices of digital cameras. The story stated that digital camera prices dipped a couple of years ago, but now are beginning to increase in price because of added features. According to the story, the average price of all digital cameras a couple of years ago was $215.00. A random sample of cameras was recently taken and entered into a spreadsheet. It was desired to test to determine if that average price of all digital cameras is now more than $215.00. The information was entered into a spreadsheet and the following printout was obtained:One-Sample T TestNull Hypothesis: μ = 215Alternative Hyp: μ > 215​95% Conf IntervalVariable Mean SE Lower Upper T DF PCamera Price 245.23 15.620 212.740 277.720 1.94 21 0.0333Is a sample size n = 22 large enough to utilize the central limit theorem in this inferential procedure?

Find the monthly payment and estimate the remaining balance (to the nearest dollar). Assume interest is on the unpaid balance.5-year car loan for $8,600 at 2.89%; remaining balance after 4 years.

Graph the function.f(x) = x + 3

Write the expression as the logarithm of a single number or expression with a coefficient of 1. Assume all variables represent positive numbers.3 ln (x + 6) – 2 ln (x2 + 7)

Solve the problem.A bottling company produces bottles that hold 10 ounces of liquid. Periodically, the company gets complaints that their bottles are not holding enough liquid. To test this claim, the bottling company randomly samples 24 bottles and finds the average amount of liquid held by the bottles is 9.8 ounces with a standard deviation of .3 ounce. Calculate the appropriate test statistic.

Solve the problem.A small private college is interested in determining the percentage of its students who live off campus and drive to class. Specifically, it was desired to determine if less than 20% of their current students live off campus and drive to class. Suppose a sample of 108 students produced a test statistic of z = -1.35. Find the p-value for the test of interest to the college.

Solve the problem.I want to test H0: p = .4 vs. Ha: p ≠ .4 using a test of hypothesis. If I concluded that p is .4 when, in fact, the true value of p is not .4, then I have made a __________.
