A simple random sample of heights of 6400Englishmen has a mean of 67.85 inches and SD 2.56 inches, while a simple random sample of heights of 1600 Australians has a mean of 68.55 inches and SD of 2.52 inches. D the data indicate that Australians are, on the average, taller than Englishmen?
A pharmaceutical company states that there is 500mg of active ingredient in each capsule for one of the medicines they manufacture. However, the FDA believes the company is purposely underfilling the capsule to save money. A sample of 20 capsules is taken and the amount of active ingredient inside is measured. The results are below: 484 460 471 512 494 529 494 485 474 502 503 538 466 495 475 529 518 464 449 489 Part 1: Construct a 95% confidence interval using toolPAK for the amount of active ingredient measured. Use the appropriate distribution, and specify the upper and lower limits of the interval. Part 2: Carefully interpret the 95% confidence interval? What if you did constructed a Confidence Interval Manually? Part 3: Does the 95% confidence interval support the FDA’s claim? Explain. Part 4: Would your answer change if the confidence level was lowered to 75%? Explain.
In forestry, the diameter of a tree at breast height is used to model the height of the tree. Silviculturists working in British Columbia’s boreal forest conducted a series of spacing trials to predict the heights of several species of trees. The data are the breast height diameters (in centimeters) and heights (in meters) for a sample of 18 white spruce trees.

Are the breast height diameters and the trees’ height linearly related? What can you infer about the relationship between the two variables? Is a linear model appropriate? b) Compare the scatter plot in (a) with the correlation coefficient…
Because of safety considerations, in May 2003 the Federal Aviation Administration (FAA) changed its guidelines for how small commuter airlines must estimate passenger weights. Under the old rule, airlines used 180 pounds as a typical passenger weight (including carry-on luggage) in warm months and 185 pounds as a typical weight in cold months. A journal reported that an airline conducted a study to estimate average passenger plus carry-on weights. They found an average summer weight of 183 pounds and a winter average of 190 pounds. Suppose that each of these estimates was based on a random sample of 100 passengers and that the sample standard deviations were 15 pounds for the summer weights and 21 pounds for the winter weights. (a) Construct a 95% confidence interval for the mean summer weight (including carry-on luggage) of this airline's passengers. (Use technology to calculate the critical value. Round your answers to three decimal places.) ( , )…
It is commonly thought that SUVs and vans are safer than cars. If an SUV and a car are in a collision, does the SUV sustain less damage and thus need a cheaper repair? We performed 7 sample crashes of SUVs at 10mph into the rear ends of stopped cars. See the table of normal data below. SUV into car SUV damage ($) Car damage ($) CRV into Civic 1721 1274 Rav4 into corolla 1434 2327 Tucson into Forte 850 3223 Tiguan into Golf 2329 2058 Patriot into Caliber 1415 3095 Escape into Focus 1470 3386 Rogue into Sentra 2884 4560 Would you be able to say that SUVs are safer since they need less repairs? Should I use: confidence intervals z-score A cause/correlation/regression or Chi-Squared hypothesis tests

Suppose you are allowed to choose any weights as long as they sum to 1. Could you always find a set of weights that would make the MSE smaller for a weighted moving average than for an unweighted moving average? Why or why not?
Item 9 At a research facility that designs rocket engines, researchers know that some engines fail to ignite as a result of fuel system error. From a random sample of 40 engines of one design, 14 failed to ignite as a result of fuel system error. From a random sample of 30 engines of a second design, 9 failed to ignite as a result of fuel system error. The researchers want to estimate the difference in the proportion of engine failures for the two designs. Which of the following is the most appropriate method to create the estimate? A one-sample z-interval for a sample proportion A A one-sample z-interval for a population proportion B A two-sample z-interval for a population proportion C A two-sample z-interval for a difference in sample proportions D A two-sample z-interval for a difference in population proportions
