Forest bathing, also called Shinrin-yoku, is the practice of taking short, leisurely walks in a forest to enhance positive health. To test the usefulness of this practice, the time forest bathing per day was recorded among eight patients with depression who subsequently showed a marked reduction in their symptoms over the last week. The data are given in the table. Time Spent in the Forest (in hours)4.34.85.13.74.35.44.04.5(a) Find the confidence limits at a 95% CI for this sample. (Round your answers to two decimal places.) (No Response) to (No Response) hours per day (b) Suppose the null hypothesis states that the average time spent forest bathing among patients is 3.5 hours per day. What would the decision be for a two-tailed hypothesis test at a 0.05 level of significance?
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.
