Is there a relation between the age difference between husbandwives and the percent of a country that is literate? Researchers found the least-squares regression between age differen 20 sxs 100. Complete parts (a) through (e) below. (a) Interpret the slope. Select the correct choice below and fill in the answer box to complete your choice. For every unit increase in literacy rate, (Type an integer or decimal. Do not round.) the age difference falls by 0.0532 units, on average. (b) Does it make sense to interpret the y-intercept? Explain. Choose the correct answer below. OA. Yesit makes sense to interpret the y-intercept because an x-value of 0 is within the realm of possibilities. B. No-it does not make sense to interpret the y-intercept because an x-value of 0 is outside the scope of the model. OC. No-it does not make sense to interpret the y-intercept because an x-value of 0 is impossible. OD. No-it does not make sense to interpret the y-intercept because a y-value of 0 is outside the scope of the model.
Correlation
Correlation defines a relationship between two independent variables. It tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
Linear Correlation
A correlation is used to determine the relationships between numerical and categorical variables. In other words, it is an indicator of how things are connected to one another. The correlation analysis is the study of how variables are related.
Regression Analysis
Regression analysis is a statistical method in which it estimates the relationship between a dependent variable and one or more independent variable. In simple terms dependent variable is called as outcome variable and independent variable is called as predictors. Regression analysis is one of the methods to find the trends in data. The independent variable used in Regression analysis is named Predictor variable. It offers data of an associated dependent variable regarding a particular outcome.
Is there a relation between the age difference between husband/wives and the percent of a country that is literate? Researchers found the least-squares regression between age difference (husband age minus wife age), y, and literacy rate (percent of the population that is literate), x, is y=−0.0532x+7.4. The model applied for 20≤x≤100.
