A random sample of 225 fathers from Littleton yielded 90 who did not help with child care. Is there enough evidence to support the claim using a 4% level of significance? Enter the Null Hypothesis for this test: HO: p=0.34 Enter the Alternative Hypothesis for this test: H1: p>.34 Is the original claim in the Null Hypothesis (HO) or the Alternative Hypothesis (H1)?
