The results of the regression analysis to estimatedelivery costsare as follows:

Which of the following statements represent a valid conclusion based on the above regression analysis output?

54.4% of transportation cost can be explained by the number of cargos.

The F-statistic is considered significant; therefore, the relationship in the regression is unlikely to happen by chance.

The p-value associated with the intercept suggests that the delivery costs are entirely variable.

Given the t-statistic, number of cargos is a poor cost driver of delivery cost.
