Reject the null hypothesis and conclude the equation is significant.
Reject the null hypothesis and conclude that the coefficient b1 is significant and keep it in the equation.
Don't reject the null hypothesis and conclude that the coefficient b1 is not significant and remove it from the equation.
Homework Answers
The p - value is greater than the significance level. Hence,
We don't reject the null hypothesis and conclude the equation is not significant and try something else.

6. In a regression analysis predicting tourism revenue ($million) using number of tourists (million), the P-value for the calculated test statistic is 0.002. At α=0.01, we I. fail to reject the null hypothesis that regression slope is equal to zero. II. reject the null hypothesis that regression slope is equal to zero. III. conclude that there is a significant relationship between the number of tourists and tourism revenue. IV. conclude that the number of tourists is NOT significant in predicting...
