Explanation Given info: The data shows that the weights of polar trees obtained from trees planted in the first region (rich and moist region) and second region (sandy and dry) due to the different treatments given to the polar trees. The significance level is 0.05. Calculation: Hypothesis test for the interaction effect between site and treatment : Null hypothesis: H 0 : There is no interaction effect between site and treatment. Alternative hypothesis: H 1 : There is an interaction effect between site and treatment. From the Minitab output, the test statistic F for “Site and Treatment” is 0.17 and the P -value is 0.915. Decision criteria for the P-value method: If the P -value ≤ α , then reject the null hypothesis ( H 0 ) . If the P -value > α , then fail to reject the null hypothesis ( H 0 ) . Conclusion: The P -value is 0.915 and the significance level is 0.05. Thus, the P -value is greater than the significance level. That is, 0.915 ( = P -value ) > 0.05 ( = α ) . Here, the null hypothesis is not rejected. Thus, there is no sufficient evidence to support the claim that the weights of polar trees are affected by an interaction between site and treatment. Hypothesis test for the row factor (Site): Null hypothesis: H 0 : The weights of the polar trees are not affected by site

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 p…
