Congratulations! To get to this point you have your project set up properly and you have all the summary statistics in the table below.
Here is a summary of where you are in your attempt to determine if the average body temperature of healthy adult males is less than the average body temperature of healthy adult females.
μ1 = the average body temperature of healthy adult females
μ2 = the average body temperature of healthy adult males
You are testing the following hypotheses with a significance level of 0.05.
H0:μ1-μ2=0
HA:μ1-μ2>0
