Answer to Problem 2.1CYU
There is sufficient evidence to support the claim of a linear relationship between pack weight and body weight in the population of the ninth-grade students at the school.
Explanation of Solution
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:
