2.20 Assortative mating: Assortative mating is a nonrandom mating pattern where individuals with similargenotypes and/or phenotypes mate with one another more frequently than what would be expected under arandom mating pattern. Researchers studying this topic collected data on eye colors of 206 Scandinavian menand their female partners. The table below summarizes the results (rows represent male eye color whilecolumns represent female eye color). For simplicity, we only include heterosexual relationships in thisexercise.BlueBrownGreenTotalBlue463028104Brown16211451Green12112851Total746270206a) What is the probability that a randomly chosen male respondent or his partner has blue eyes?

An article reported that in a particular year, there were 717 bicyclists killed on public roadways in a particular country, and that the average age of the cyclists killed was 43 years. These figures were based on an analysis of the records of all traffic-related deaths of bicyclists on public roadways of that country. (a) Does the group of 717 bicycle fatalities represent a census or a sample of the bicycle fatalities for that year? O a census O a sample (b) If the population of interest is bicycle traffic fatalities for this particular year, is the given average age of 43 years a number that describes a sample or a number that describes the population? O a number that describes a sample O a number that describes the population
A fitness course claims that it can improve an individual's physical ability. To test the effect of a physical fitness course on one's physical ability, the number of sit-ups that a person could do in one minute, both before and after the course, was recorded. Ten individuals are randomly selected to participate in the course. The results are displayed in the following table. Can it be concluded, from the data, that participation in the physical fitness course resulted in significant improvement? Let d=(number of sit-ups that can be done after taking the course)−(number of sit-ups that can be done prior to taking the course)d=(number of sit-ups that can be done after taking the course)−(number of sit-ups that can be done prior to taking the course). Use a significance level of α=0.05α=0.05 for the test. Assume that the numbers of sit-ups are normally distributed for the population both before and after taking the fitness course.

A study compares students who use a website and students who do not use the website. In addition to asking the students in the samples about GPA, each student was also asked how many hours he or she spent studying each day. The two samples (141 students who were users of the website and 68 students who were not users of the website) were independently selected from students at a large, public university. Although the samples were not selected at random, they were selected to be representative of the two populations. n USE SALT For the sample of users of the website, the mean number of hours studied per day was 1.46 hours and the standard deviation was 0.83 hours. For the sample of students who do not use the website, the mean was 2.77 hours and the standard deviation was 0.99 hours. Do these sample data provide convincing evidence that the mean time spent studying for users of the website at this university is less than the mean time spent studying by students at the university who do…

According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), and the National Institutes of Health (NIH), 42% of college students nationwide engage in “binge drinking” behavior, having 5 or more drinks in one occasion during the past two weeks. A college president wonders if the proportion of students enrolled at her college that binge drink is actually different than the national proportion. In a commissioned study, 364 students are selected randomly from a list of all students enrolled at the college. Of these, 136 admitted to having engaged in binge drinking. Calculate the statistic for this sample. Calculate the standard error for this sample. Verify that we can use a normal distribution for this sample. By hand calculate a 90% confidence interval for the proportion of all students at this college that engage in binge drinking. Show all work. Interpret the results of your confidence interval in the context of the…
1. A paper on men's and women's eating behaviors describes an experiment in which 74 men were assigned at random to one of four treatments. viewed slides of fit, muscular men viewed slides of fit, muscular men accompanied by diet and fitness-related text viewed slides of fit, muscular men accompanied by text not related to diet and fitness did not view any slides The participants then went to a room to complete a questionnaire. In this room, bowls of pretzels were set out on the tables. A research assistant noted how many pretzels were consumed by each participant while completing the questionnaire. Data consistent with summary quantities given in the paper are given in the table.

Researchers believed that floral scent can sometimes improve a person's learning ability. They set up an experiment in which each of 22 subjects completed sets of pencil-and-paper mazes. Each subject wore a floral-scented mask and an unscented mask, where the order in which the masks were presented was random. The researchers measured the time to complete the sets of mazes. This experimental design is: a matched pairs design. a confounding design. a double-blind design. a completely randomized design.
