here's a reference on CV which, i believe, is called the coefficient of variation.

https://www.investopedia.com/terms/c/coefficientofvariation.asp#:~:text=Key%20Takeaways-,The%20coefficient%20of%20variation%20(CV)%20is%20a%20statistical%20measure%20of,of%20return%20expected%20from%20investments.

based on this reference, it is the standard deviation divided by the mean.

your problem gives the mean as 78.5 with a standard deviation of 6.2.

the CV would be equal to standard deviation / mean = 6.2 / 78.5 = .0789808917.

round as required.
