In questions 4-7, use the following printout of the linear regression relating the age in days of 30 randomly selected babies under the age of 2 and their weights in pounds:
Does this analysis provide support for rejecting the null hypothesis that the slope of the regression line is 0 at the 5% level of significance? Why is this?
No, the slope in this analysis is less than 0.95.
Yes, the P-value for the slope in the analysis is shown as 0.
Yes, the P-value for the slope in the analysis is less than the significance level of 0.05.
Yes, this analysis shows that the true regression slope must be 0.842 with more than 95% certainty.
No, the test statistic for the significance test is too small to meet the stated level of significance.
Homework Answers
Yes, the P-value for the slope in the analysis is less than the significance level of 0.05
This is correct option
