According to a Harvard Health Publishing article, the normal body temperature may be  lower than 98.6 degrees according to data samples from the past 160 years. A sample of 12  random adults from a biology class had the following temperatures in Fahrenheit: 96.6; 97.5; 98.9; 96.4; 98.1; 98.9; 97.6; 97.8; 98.1; 97.9; 96.7; 98.6 At α = 0.05, is there evidence to support the traditional belief that the average body  temperature is 98.6 degrees?
