Question 1180798: 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. Answer by robertb(5830) (Show Source):
c) The probability of committing a Type 1 error is equal to the the significance level, 5%.
d) When H0 is rejected, we say that the BMI is significantly different from 8.2.
e) If the sample BMI is greater than 8.2, then the rejection region is on the right tail.
If the sample BMI is less than 8.2, then the rejection region is on the left tail.
