In the last homework, you calculated a regression line for the height (slidewalk to roof) of notable tall buildings in America by the number of stories of the building (beginning at street level). Stories Height (in feet) 57 1050 28 428 26 362 40 529 60 790 22 401 38 380 110 1454 100 1127 46 700 a. Do the data provide sufficient evidence at the 5% significance level that the slope is not zero? State your null and alternative hypotheses. Ho Select an anawer v | 7 w HSelect an answer b. test statistic t C.p-value (Hint: Enter 0 is less than 0.0001)
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.
