- Four different beverages are sold at a fast-food restaurant soft drinks, tea, coffee, and bottled water. Answer parts (a) and (b) a. Explain why the type of beverage sold is an example of a categorical variable. Choose the correct answer below OA Type of beverage sold is a categorical variable because the values of the variable arise from a measuring process OB. Type of beverage sold is a categorical variable because the values of the variable can only be placed into categories OC. Type of beverage sold is a categorical variable because the values of the variable arise from a counting process OD. Type of beverage sold is a categorical variable because the values of the variable represent quanteles b. Explain why the type of beverage is a nominal-scaled variable Choose the correct answer below OA Type of beverage sold is a nominal-scaled variable because there are no rankings for the different values of the vanable OB Type of beverage sold is a nominal-scaled variable because the…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.Express the alternative hypothesis in symbolic form. A psychologist claims that the mean amount of time (in hours) that females spend in talk therapy is more than that of men. Assume that two samples are independent. Let the female talk therapy times be the first population and the male talk therapy times be the second population.

- We discuss how to test for an association between two categorical variables in Section 6.8. A marine research team records the number of fish from 3 species that they find at different depth categories in the ocean. They are interested in assessing whether or not there is a relationship between the depth category (close to surface, mid-level, ocean floor) and the fish species found (species A, species B, species C). A two-way table showing the classification of a sample of 150 observations is given below. If the variables for the ocean depth category and the species are independent, how would you calculate the expected number of fish that are at the mid-level and from species C? Expected number =The level of water usage of 250 houses was rated in a survey as low, medium or high and the size of the houses as small, standard or large. The variables,level of water usage and size of house, as recorded in this survey, are a. both numerical variables. b. both categorical variables. c. neither numerical nor categorical variables. d. numerical and categorical variables respectively.i need help with this question
- We are interested in looking at the effect of a baseball player’s free agent status on their salary. We look at 337 baseball players and categorize them as either having a high salary (above 2 million) or not, and as either being free agents or not. ------------------------------ You also wonder if having a high batting average affects the salary of baseball players. You classify all 370 baseball players as having a high batting average if it is over .300. 1. The given χ2test table gives many test statistics. The row we want to look at is labeled Pearson Chi-Square. Give the test statistic, the degrees of freedom, and the p-value. 2. At a significance level of .05, what can you conclude in the context of this problem?catagorize the following variables as being qualitative and quantitative? 1, response time 2, the type of drinks ordered by seven people at a bar 3, rating of job satisfaction 4, favourite color 5, the occcupation of the father of children in a third grade class 6, nomber of words remamberedRead the scenario below to determine which one of the five areas of construct validity (content, response processes, internal consistency, relationship to other variables and consequences) is of most concern. Researchers developed a new and different exam for admission into graduate school. Researchers constructed a Table of Specifications for the new exam.
