College tuition: The mean annual tuition and fees in the 2013-2014 academic year for a sample of 22 private colleges in California was $38,750 with a standard deviation of $7200. A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California differs from $35,000? Use the a=0.01 level of significance and the P-value method with the TI-84 Plus calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. Ho: H = 35,000 H:u + 35,000 This hypothesis test is a two-tailed test. Part: 1 / 4 Part 2 of 4 Compute the P-value. Round the P-value to at least four decimal places. P-value =
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.
