Say we have a component in a software project that has $1800$ lines of code $($LOC$).$ We do a review and uncover $30$ minor errors and $8$ major errors. The effort to correct a minor error is $5$ person$-$hours while a major errors is $20$ person$-$hours. Errors uncovered during component testing require an average of $50$ person$-$hours to find and correct.Calculate the effort saved per error through the review process $(2$ points$)$Say that the project has an average error density of $3$ errors per $50$ LOC. Describe what the implications of this are in this scenario $(2$ points$)$
