The CEO of an airport hypothesizes that the variance in the number of passengers for American airports is greater than the variance in the number of passengers for foreign airports. At alpha = 0.05, is there enough evidence to support the hypothesis. Data in millions of passengers per year: American airports: 36.8 72.4 60.5 73.5 61.2 40.1 Foreign airports: 60.7 42.7 51.2 38.6A. Compute the test statistic, rounding the sample standard deviations to 4 decimal places and the F statistic to 3 decimal places. B. Determine the critical value. C. Determine the p value, rounded to 4 decimal places. D. What is the decision? Fail to Reject HoReject HoAccept H1Reject H1
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.
