Include a formal decision statement regarding the Null and a formal interpretation of the results.

Problem #1
Dr. Therma claims that 17- year-olds have an average body temperature that is higher than the commonly accepted average human temperature of 98.6 degrees Fahrenheit. A simple random sample of 250 17- year-olds is selected. The average temperature of the sample is found to be 98.9 degrees, with standard deviation of 0.6 degrees. At the 0.05 alpha level, test that the sample’s mean temperature is higher than 98.6 degrees. Include a formal decision statement regarding the Null and a formal interpretation of the results.
