Answer:
This difference is not significant
Step-by-step explanation:
It should be understood that, Jerry assumptions that hands-on experience was important than a college degree, and that, having a college degree would result in a lower salary were very wrong.
And since Jerry has discovered that he had made wrong assumptions, and a costly mistake of having only the hand-on experience and not a college degree, he will try to find words that can be used to console himself. And that is why, he will conclude that the difference is not significant.
