In a survey of 1000 randomly selected adults in the US, participants were asked what their most favorite and their least favorite subject was when they were in school. In what might seem to be a contradiction, math was chosen more often than any other subject in both categories (AP, 2005)! Math was chosen by 230 responders as their favorite subject. Construct a 95% confidence interval for the proportion of US adults for whom math was their favorite subject in school. a) b) How many adults should be surveyed in order to have a margin of error of 1%?

A survey was conducted to determine whether hours of sleep per night are independent of age. A sample of individuals was asked to indicate the number of hours of sleep per night with categorical options: fewer than 6 hours, 6 to 6.9 hours, 7 to 7.9 hours, and 8 hours or more. Later in the survey, the individuals were asked to indicate their age with categorical options: age 39 or younger and age 40 or older. Sample data follow.

Explain what the statements below mean:A)A Rasmussen Reports national survey of 1000 adult Americans found that 18% dreaded Valentine's Day. The margin of error for the survey was 4.5 percentage points with 95% confidence. B)A Gallup poll of 547 adults Americans employed full or part time asked, "Generally speaking, would you say your commute to work is - very stressful, somewhat stressful, not that stressful at all?" Gallup reported that 24% of American workers said that their commute was "very" or "somewhat" stressful. The margin of error was 4 percentage points with 95% confidence.
What statistical test would a researcher use to test the following research hypothesis: Individuals who report less favorable attitudes toward the police are more likely to be sentenced to higher security prisons. Attitudes measured as 1 = very favorable, 2 = somewhat favorable, 3 = somewhat not favorable, and 4 = not at all favorable. Sentences measured as 1 = minimum, 2 = medium, and 3 = maximum.

A high school track coach wanted to test whether giving the students an energy drink could affect performance during the 100 meter race. The coach split the 26 boys into two equal sized groups, where Group 1 was given the energy drink and Group 2 was not. The 100 meter race times were recorded during practice and shown in the table below. What inference can be made about the results? Group 1 Group 2 12.2 13 12.5 12.3 13.3 12.8 12.9 13 13 13.8 12.1 13 13 13 13 13 12.1 13 13 13 12.1 13 12.8 13 13 12.6 Mean: 12.7 Mean: 13 Since the simulation shows ( many cases or free cases )? where a mean difference of ( solve for this answer ) or less occurred when the groups were re-randomized, it can be inferred that the mean difference observed in the study was ( very possibly or very unlikely ) ?due to the random assignment of participants into groups, so the results of the study are (…
A survey was done where one question asked of the participants was, “How many meals per week do you typically eat at a restaurant”. The numerical answers ranged from a low of 0 to a high of 12. How could you ask a question that would treat this as a categorical variable? Give the question and give the choices for the answer.
