- Researchers created two test sheets, each sheet showing 2020photos of the faces of dog‑owner pairs. The two sheets were equivalent with respect to breed, diversity of appearance, and gender of owners. On the first sheet the dogs were matched with their owners, while on the second sheet the dogs and owners were deliberately mismatched. Three experiments were conducted, and in all experiments, subjects were asked to "choose the set of dog‑owner pairs that resemble each other, Sheet 11or Sheet 22," and were simply told the aim of the research was a "survey on dog‑owner relationships." In the first experiment, the original sheets were shown to subjects; in the second experiment, just the mouth region of the owners was blacked out in all the pictures on both sheets; while in the third experiment, just the "eye region" of the owners was blacked out. Subjects were assigned at random to the three experimental groups, and in each experiment, the number of subjects who selected the sheet with…A fair die with its faces numbered from 1 to 6 will be rolled. Which of the following is the best interpretation of theprobability that the number landing face up will be less than 3 ?(A) For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 1/3.(B) For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 1/2.(C) For many rolls of the die, the long-run relative frequency of a number less than 3 landing face up is 2/3.(D) For three rolls of the die, a number less than 3 will land face up one time.(E) It will take three rolls of the die before a number less than 3 lands face up for the first time.Suppose that a researcher is interested in the average standardized test score for fifth graders in a local school district. The fifth graders at a specific school would comprise a ___________ and their average test score would be a ___________.
- Determine the mean waiting time W for an M/M/2 system when lambda = 2 and μ = 1.2. Compare this with the mean waiting time in an M/M/1 system whose arrival rate is lambda = 1 and service rate is μ = 1.2. Since the arrival rate per server is the same in both cases and service times don’t vary, should the wait times be the same in both cases?suppose that the mean time for a certain car to go from 0 to 60 miles per hour was 8.6 seconds. Suppose that you want to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer than 8.6 secons. What would you use for the alternative hypothesis?If the alleles A and B of the cystic fibrosis gene occur in a population with frequencies p and 1 - p (where pis between 0 and 1), then the frequency of heterozygous carriers (carriers with both alleles) is 2p(l - p).
