To check: Whether the average amount of cola that is filled in bottle is different from 300ml by conducting the hypothesis testing.
Answer to Problem 80E
No, it cannot be concluded that the average amount of cola that is filled in bottle is different from 300ml.
Explanation of Solution
Given:
The data set is:
299.4 |
297.7 |
301 |
298.9 |
300.2 |
297 |
Formula used:
The test statistic is computed as:
Here,
Calculation:
Here,
The null and alternative hypotheses are:
The obtained excel output is:
Assume level of significance to be 0.05.
Here, p-value is 0.1760. Here, p-value > level of significance. Thus, the decision is not to reject the null hypothesis.
Conclusion:
Thus, at 5% significance level there is insufficient evidence to conclude that average amount of cola that is filled in bottle is different from 300ml.
