The p-value associated with this test is the upper tail area of the F distribution with p = 2 numerator deg of freedom and n- p - 1 = 7 denominator degrees of freedom. Use technology to find the p-value for F = 43.57, rounding the result to three decimal places. %3D %3D p-value =
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.

Step 6
The p-value associated with this test is the upper tail area of the F distribution with p = 2 numerator degrees
of freedom and n - p- 1 = 7 denominator degrees of freedom. Use technology to find the p-value for
F= 43.57, rounding the result to three decimal places.
p-value
The conclusion is made by comparing a and the found p-value. If the p-value is less than or equal to a, the
null hypothesis is rejected in favor of the alternative. If the p-value is greater than a, we fail to reject the null
hypothesis. Recall the hypotheses being tested.
HoiBq=B2=D0
H: One or more of the parameters is not equal to zero.
a
The p-value is
less than or equal to
0.05. Therefore, we
reject
V the null hypothesis and
conclude that there
is
sufficient evidence to conclude that the overall model is significant.
