State the hypothesis in a sentence (for example): The average body temperature of people in our class is 98.6 degrees Fahrenheit. Express that idea using scientific notation (For example: A one-sample test for temperature would read): Null Hypothesis - Ho: u = 98.6, Alternate Hypothesis - HA: H # 98.6 Appropriate t-test used to evaluate the hypothesis Alpha (a) level . P-value State in a sentence or two whether the hypothesis is rejected or if there is not enough evidence to reject the null hypotheses and what the results mean.
