The following samples of fish were taken of their weight, in grams, at a fishery before the young fish are restocked into Cane Creek Lake. From experience, we know that very few fish under 4 grams will survive. Guidelines for restocking require the sample to have a mean greater than 5 with an unbiased variance of the mean to be less than (mean - 4) / 2
Determine the mean and an unbiased variance of this sampling:
{ 4 , 5 , 8 , 5 , 7 , 5 , 7 , 7 }
