Yоu hаve just finished weighing а pаn оf tadpоles at the conclusion of your experiment in which you sought to determine whether tadpoles that were fed the meat-based diet grew significantly larger than tadpoles that were fed boiled lettuce. This pan of tadpoles was fed the meat-based diet. You used an electronic balance to weigh your tadpoles, so youhave not estimated the last digit of the measurements. For practical purposes, you will assess a small data set of eight tadpoles. The individual weights of the tadpoles were as follows:•55.99 mg•56.45 mg•58.67 mg•56.15 mg•58.56 mg•60.43 mg•59.11 mg•61.33 mgWhat is the mean of this sample?
