Student conducts a high temperature experiment using a thermister with a guaranteed accuracy of +/- 1.3 degrees fahrenheit. the student takes an initial set of 11 measurements, and calculates a sample average of 224 and a sample deviation of 19.8 degrees. assuming a confidence level of 99%, estimate the total number of samples needed to ensure a total measurement uncertainty less than 3.5 degrees. (the number of samples should be an integer)
