Q.no.3 A random sample of 34 participants in a Zumba dance class had their heart rates measured before and after a moderate 10-minute workout. The following data correspond to the increase in each individual’s heart rate (in beats per minute): 59, 70, 57, 42, 57, 59, 41, 54, 44, 36, 59, 61, 52, 42, 41, 32, 60, 54, 52, 53, 51, 47, 62, 62, 44, 69, 50, 37, 50, 54, 48, 52, 61, 45. a)What is the point estimate of the corresponding population mean? b) Make a 98% confidence interval for the average increase in a person’s heart rate after a moderate 10-minute Zumba workout.?
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.
