In an agricultural experiment, the effects of two fertilizers on the production of oranges were measured. Fourteen randomly selected plots of land were treated with fertilizer A, and 10 randomly selected plots were treated with fertilizer B. The number of pounds of harvested fruit was measured from each plot. Following are the results. Fertilizer A 473 507 526 479 477 468 516 467 519 523 483 540 518 488Fertilizer B 455 501 470 420 483 419 468 476 459 513Assume that the populations are approximately normal. Construct a 95% confidence interval for the difference between the mean yields for the two types of fertilizer. Interpret the results.
A trucking firm is considering the installation of a new, low-restriction engine air filter for its long-haul trucks, but doesn’t want to make the switch unless the new filter can be shown to improve the fuel economy of these vehicles. A test is set up in which each of 10 trucks makes the same run twice once with the old filtration system and once with the new version. Given the sample results shown below: Truck Number Current Filter (mpg) New Filter (mpg) 1 7.6 7.3 2 4.1 7.2 3 10.4 6.8 4 6.9 10.6 5 5.6 8.8 6 7.9 8.7 7 5.4 5.7 8 5.7 8.7 9 5.5 8.9 10 5.3 7.1 If the null and alternative hypotheses can be used to decide whether the new filtration system could be superior. Calculate the standardized test statistic.
In a study to compare two different methods of teaching reading, a class of 20 childrenwas divided into two groups at random. Each group was taught reading using onemethod. After six months the two groups were given the same test. One pupil in thefrst group was ill and missed the test. The scores are given below.Method 1 80 85 79 81 89 73 50 71 76Method 2 79 62 75 68 62 73 76 81 73 61 Hence draw box-and-whisker plots for the two groups using the same scale
SPSS: In order to compare a new variety of wheat with a standard, an experiment is used with six plots receiving the new variety and ten plots receiving the standard. The yields (t/ha) are as follows: New variety: 2.6 2.1 2.5 2.4 1.9 2.3 Standard variety: 1.7 2.1 2.0 1.8 2.3 1.6 2.0 2.1 2.2 1.9 a) Identify the model for comparing the wheat yield. b) Is there evidence at the 5% significance level that the yield of the new variety is higher? c) Estimate the difference in yield with 95% confidence.

A student decides to spin a dime and determine the proportion of times it lands on heads. The student spins the dime 25 times and records that it lands on heads 17 times. Let p = the true proportion of times the dime would land on heads when spun. Under the assumption that the true proportion is 0.5, 100 simulated proportions for samples of size 25 is shown in the dotplot. Using the dotplot, is there evidence that the proportion of times a spun dime lands on heads is greater than 0.5? A) Yes, a proportion of 0.68 proves that the true proportion of heads is greater than 0.5. B) Yes, a proportion of 0.68 only occurred once out of 100 simulated proportions; therefore, there is sufficient evidence that the true proportion of heads is greater than 0.5. C) No, a proportion of 0.68 is only 0.18 more than 0.5; therefore, there is insufficient evidence that the true proportion of heads is greater than 0.5. D) No, a proportion of 0.68 or more occurred 7 times out of 100 simulated…
