pl ticuid teacher s ELA proficiency scores more than the other PDT's? 03. An economist is curious to know if level of education has an impact on the per capita income of an individual. He finds out that individual's age also impacts their per capita income. He administers survey to 100 participants. The economist wants to following research question: Is there a difference in per capita income (measured in $) depending on level of participant? The SPSS outputs are provided below. Respond to the following questions based on the SPSS outputs. education after accounting for differences in the age of the a. State the null and alternate hypothesis. 1 point b. What is/are the independent variable(s) and how many levels do they have? 1 point c. What is the dependent variable? 1 point d. What is the covariate? 1 point e. Comment on the homogeneity of variance assumption. 1 point f. Does age have a significant influence on per capita income? 1 point g. Does education level have a significant influence on per capita income? 1 point h. Are there any statistically significant differences in per capita income based on level o education? 1 point Write up the summary results in a scholarly manner. 2 points i. Between-Subjects Factors 125 Education Level 2 3 25 4 25 Levene's Test of Equality of Variances df1 df2 S 022 3 96 Tests the null hypothesis that the error variance of the dependent variable is equal across groups a. Design: Intercept+Age+Education Level 995Explanation / Answer
a. H0: The level of education has not impact on the per capita income of an individual
H1: The level of education has impact on the per capita income of an individual
b. There are two independent variables that is, age and education level
In education level, there are 3 levels
c. dependent variable: Per Capita Income
e. Here P value from Leven's Test = 0.995 > alpha 0.05, so we accept H0
Thus we conclude that it satisfies the homogenity of variances assumption.
f) P-value of Age is 0.027 which is < alpha 0.05, so we reject H0
Thus we conclude that age have a significant influence on per capita income
g) P-value of Age is 0.244 which is > alpha 0.05, so we do not reject H0
Thus we conclude that education level have not significant influence on per capita income
h) No, there is no significantly differences in per capital income based on level of education
