(c) Suppose that the social researcher decided to use gender as a distinct feature. Also suppose that the population X consists of m males and f females (where m+f = X), then the relative size m/X and f/X is used for proportionate allocation. Suppose Y samples must be selected for this study, and then mY/X and fY/X is to be selected within respect stratum. Random sampling can be used within each stratum. (d) There should be 6 variables in her data set, namely, Household Residents, Full Time Workers, Number of Children, Proportion of Females, Household Income and Visits made to centre.
Answer: False Difficulty: Medium 5. The sampling distribution of a sample statistic is the probability distribution of the population of all possible values of the sample statistic. Answer: True Difficulty: Easy 6. A sample statistic is an unbiased point estimate of a population parameter if the mean of the populations of all possible values of the sample statistic equals the population parameter. Answer: True Difficulty: Medium 7.
Which relationship is the closest to this r value? Provide a rationale for your answer. Variables 6 and 7 have the weakest correlation (r = -0.02). This is the relationship between emotion and avoidance, which are coping styles. The relationship which is closest to this r value is variables 4 and 7, which represents negative items and avoidance.
Is there a relationship between total expenses and number of admissions? MSM= 29881.226 F Value = 11.691383 Using F table for (DFM, DFE) = (1,12) F value = 4.75 Significance of F =.049943034 Yes, the model is statistically significant at 5% level & Yes there is a relationship between total expenses and number of admissions. 2. The Housing Data tab of the Chapter 4 Assignment Data spreadsheet contains information on the sales prices of houses, their square footage, and their age. Perform a regression on this data with sales price as the Y variable, and answer the following questions.
In class we have discussed many theories that relate to the Craig Price (aka Warwick Slasher) story. Social Disorganization Theory can relate because his delinquency tied to socioeconomic conditions. Cultural Deviance Theory could also be related to his story because he came from a lower class. Socialization can have an effect on delinquency as well. I believe the theory that would be the most applicable to the case is the developmental theory.
“Social inequality refers to the unequal distribution of social, political, and economic resources within a social collective, such as a nation.” (Krieken, R. et al. 2014, p. 204). Sociologists have identified a number of variables which have an influence on social inequality. These include; class, status, power, social capital and cultural capital. Krieken, R. et al.
The alternative hypothesis is the hypothesis that sample observations are influenced by some non-random cause. 3. What is a test statistic? (0.5 points) A statistic is a single measure of some attribute of a sample. It is calculated by applying a function (statistical algorithm) to the values of the items of the sample, which are known together as a set of data.
Discuss surplus-enhancing transactions in markets 6. Explain how elasticity affects the way in which the burden of a per-unit tax is shared between buyers and sellers 7. Explain how elasticity affects the size of the deadweight loss created by a per-unit tax **NOTE: All of chapter 5 of Hubbard, Garnett, Lewis and O’Brien (2011) Microeconomics, 2nd edition, Pearson is required reading. 1. Consumer surplus The difference between the highest price a consumer is willing to pay for a good or service, and the price they actually pay.
b) How could you know that Q* in part (a) minimizes rather than maximizes AVC? 3. The Bound's Inc. has the following total cost (TC) function (where Q is the number of units produced and sold): TC = 50 + 100Q – 6Q2 + 0.5Q3 a) Determine the output level (Q*) that minimizes marginal cost (MC). b) How could you know that the value of Q* in part (a) minimizes rather than maximizes MC? 4.
In factorial research design, the effects of two or more variables are examined at the same time by making groupings of every combination of the variables. It would be analyzed with what is called a two-way analysis of variance (two-way ANOVA) because it considers the effects of two variables that divide the groups. Two-way ANOVA can be used to test the effects of variables on the dependent variables which is the lack of awareness differences based on gender and age, and interaction effects of lack of awareness to the quality of life and vice
