Identify the null hypothesis, alternative hypothesis, test statistic, conclusion about the null hypothesis, and final conclusion that addresses the original claim. 3) An article in a journal reports that 34% of American fathers take no responsibility for child care. A researcher claims that the figure is higher for fathers in the town of Littleton. A random sample of 234 fathers from Littleton yielded 96 who did not help with child care. Test the researcher's claim at the 0.05 significance level. H0 = HA = Z = Conclusion:

An article in a journal reports that 34% of American fathers take no responsibility for child care. A researcher claims that the figure is higher for fathers in the town of Littleton. A random sample of 225 fathers from Littleton yielded 97 who did not help with child care. Using a 0.05 level of significance, test the claim that the proportion is at least 34%. Please answer all parts related to this question: 1. State the null hypothesis H0: _____________ 2. State the alternative hypothesis H1: _____________ 3. What is the test statistic used for the test (z or t) and its value (round to 2 places)? 4. State the significance or alpha (α) level. 5. Determine the p-value (round to 4 places). 6. Do you or do you not reject the null hypothesis? Why? 7. Write a clear conclusion using a complete sentence.
