Summative Which of the following conclusions about the changes in average annua global temperatures from 1990 to present is BEST supported by the data in Figure 1 ? Each year, global temperature has decreased. The global temperature difference has increased from about \( 0.4^{\circ} \mathrm{C} \) to \( 0.9^{\circ} \mathrm{C} \). The global temperature difference in 1990 was greater than the difference in 2010. ex-let \( x \) be arandom variable with mean \( E(x)=w \). Defin the function \( f(x) \) as \( f(\alpha)=E(x-\alpha)^{2} \) Find the value of \( \alpha \) that minu \( f(x) \). You did a chi square test in SPSS. How would you come up with a decision to make with regard to the \( H_{0} \) ? (A) If confidence level lies between the \( p \)-value and \( X^{2} \) obt the \( H_{0} \) can be rejected (he \( H_{0} \) can be rejected (C) If the \( x^{2} \) obt is greater than the critical value, the \( H_{0} \) can be retained (D) If \( p>a \), the \( H_{0} \) can be rejected In Cramer's V, a positive relationship means... A That as the independent variable increases, the dependent variable decreases (B) That as the independent variable decreases, the dependent variable remains static (C) That as the independent variable remains unchanged, so does the dependent variable (D) That as the independent variable increases, so does the dependent variable When two variables are statistically dependent . . . A The dependent variable has predictive power over the independent variable (B) The independent variable does not have predictive power over the dependent variable (C) The dependent variable does not have predictive power over the independent variable (D) The independent variable has predictive power over the dependent variable nother city experiences 12 deaths for each thousand people. What is the death rate (as a percentage and thousand)? When two variables are statistically dependent... A The dependent variable has predictive power over the independent variable (C) The dependent variable does not have predictive power over the independent variable (D) The independent variable has predictive power over the dependent variable If a distribution follows the binomial distribution with \( n=50 \) and probability of success of 0.25 , calculate the mean and variance. The chi-square test of independence is . . . (A) The hypothesis test appropriate when the independent variable is categorical, but the dependent variable is continuous (B) The hypothesis test appropriate for continuous data (C) The hypothesis test appropriate when the independent variable and dependent variable are continuous (D) The hypothesis test appropriate when the independent variable and dependent variable are categorical In chi square analysis, it is possible to finda statistically significant relationship but an effect size very lo A) True B) False
