Question 1180880: A social worker wants to test (𝛼=0.05) whether the average body mass index
(BMI) of the students under feeding program is different from 8.2 kg.
a) State the H0 and H1in words.
b) State the H0 and H1 in symbols.
c) What is the probability of committing Type I error?
d) State the conclusion when H0 is rejected.
e) Determine the direction and the tail (if applicable) to be used.
Please help me with this Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 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
