Math Problem Statement
From the p-value as reported above, we can conclude that the decision of the test is:
Answer 9 Question 1 Accept H0Reject H0Do not accept H0Do not reject H0
What is the conclusion of the test?
a. There is not enough evidence that the age of the artists involved in a recent auction of new art is distributed differently than the given table of probabilities
b. There is evidence that the age of the artists and type of artwork are independent
c. There is evidence that the age of the artists involved in a recent auction of new art is distributed according to the given table of probabilities
d. There is evidence that the age of the artists and type of artwork are associated
e. There is not evidence that the age of the artists and type of artwork are associated
f. There is evidence that the age of the artists involved in a recent auction of new art is not distributed according to the given table of probabilities
Solution
To answer this question properly, we need to break down two parts:
- The test decision:
- If the p-value is smaller than the significance level (often denoted as , such as 0.05), we reject the null hypothesis .
- If the p-value is greater than the significance level, we do not reject the null hypothesis.
Given the options:
- "Accept H0" is typically not recommended wording in hypothesis testing because we never "accept" ; we simply fail to reject it if there’s insufficient evidence.
- "Reject H0" means there is enough evidence against the null hypothesis.
- "Do not reject H0" means there is not enough evidence to reject it.
Conclusion:
- The interpretation of the conclusion depends on the context of the hypothesis:
- If we reject , it means there is sufficient evidence to support the alternative hypothesis .
- If we do not reject , it means there is not sufficient evidence to support the alternative hypothesis, so the null hypothesis stands.
Given the conclusions related to the test options:
- a. There is not enough evidence that the age of the artists is distributed differently from the given table of probabilities (this would align with "do not reject " if the test is for distribution).
- b. There is evidence that age and artwork type are independent (depends on the context of the hypothesis, possibly a chi-square independence test).
- c. There is evidence that the age is distributed according to the table of probabilities (would align with rejecting the alternative hypothesis if it were framed differently).
- d. There is evidence that age and artwork type are associated (again relevant for an association test, depending on ).
- e. There is no evidence of association (would align with failing to reject ).
- f. There is evidence that the age is not distributed according to the table (this aligns with rejecting ).
So, without seeing the exact p-value and the hypothesis, the correct test decision might be:
- If the p-value is low (below the significance level), reject (so answers f or d would be possible).
- If the p-value is high, do not reject (so answers a or e would apply).
Follow-up Questions:
- How is the null hypothesis typically framed in this kind of statistical test?
- What is the significance level used in this hypothesis test?
- What kind of test (e.g., chi-square test, goodness-of-fit test) is being performed?
- What are the consequences of rejecting versus not rejecting ?
- How does the p-value relate to practical significance in this context?
Tip: Always check the assumptions of your statistical test (like independence or normality) before interpreting the p-value.
