A simple random sample of men who regularly work out at Mitch's Gym is obtained and their r pulse rates (in beats per minute) are listed below. Use a 0.1 significance level to test the claim t these sample pulse rates come from a population with a mean less than 72 beats per minute (t mean resting pulse rate for men). Assume that the standard deviation of the resting pulse rate men who work out at Mitch's Gym is known to be 8 beats per minute. Use the p-value method testing hypotheses.
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.
