Question
A company that makes spirits states that the mean alcohol content per one-liter bottle of its vodka is 500 ml. You believe that they are incorrect and decide to test their claim. During your tests, you find that a random sample of 33 one-liter bottles of vodka has a mean alcohol content of 523.59 ml with a standard deviation of 93.58 ml. Based on this information, you decide to:
a: Reject the null at the 0.01 level of significance
b. Fail to reject the null at the 0.05 level of significance
c. Normality not established; do not test
d. Reject the null at the 0.05 level of significance
Explanation / Answer
The statistical software output for this problem is:
One sample T summary hypothesis test:
: Mean of population
H0 : = 500
HA : 500
Hypothesis test results:
Since p - value is greater than 0.05, we fail to reject the null at the 0.05 level of significance.
Option B is correct.
