State the null hypothesis, H0, and the alternative hypothesis. Ha, in terms of the appropriate parameter (μ or p). j. Private universities' mean tuition cost is more than $20,000 per year. [______]
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.

In this lab we cover the important technique in
is a process that uses sample statistics to test a claim about the value of a population parameter. Researchers in
fields such as medicine, psychology, and business rely on hypothesis testing to make informed decisions about
new medicines, treatments, and marketing strategies.
Some of the following statements refer to the null hypothesis, some to the alternate hypothesis.
State the null hypothesis, H0, and the alternative hypothesis. Ha, in terms of the appropriate parameter (μ or p).
