Concept explainers
(a)
To explain is there statistically significant evidence of a negative linear relationship between wine consumption and heart disease deaths in the population of countries and carry out an appropriate test at the
(a)
Answer to Problem 19E
There is sufficient evidence to support the claim of a negative linear relationship between wine consumption and heart disease deaths in the population of countries.
Explanation of Solution
Now, we will use the excel technology to find output by first selecting the data and then going to the data analysis option and when the drop box appear select the ANOVA test, thus, using the technology we will find the following output as:
It is given in output that:
Thus, we define the hypothesis by:
Thus, the value of the test statistics is as:
And the degrees of freedom is:
Thus, the P-value is as:
As we know that if the P-value is less than or equal to the significance level, then the null hypothesis is rejected as:
Thus, we conclude that there is sufficient evidence to support the claim of a negative linear relationship between wine consumption and heart disease deaths in the population of countries.
