Ho: The true mean of the BMI is 8.2 kg. mu=8.2
Ha: The true mean of the BMI is not 8.2 kg. mu not= 8.2; mu NE 8.2
The probability of making a Type I error is alpha, or 0.05.
If Ho is rejected, the conclusion is the true mean of the BMI is not 8.2 kg.
This is a two-tailed test, since the hypothesis may be rejected in either direction
