Since Fall Biolab has been studying human -D-crystallin (HGDC) for so long, we know that the melting temperature for wild-type HGDC is 84.3 C with a standard deviation of 2.1 C. You decide to analyze the mutant you generated and get the data below where each number is the melting temperature for a different trial.
