Some of the statements below refer to the null hypothesis, some to the alternate hypothesis. State the null hypothesis, Ho, and the alternative hypothesis, Ha, in terms of the appropriate parameter (u or p). Part (a) The mean number of years Americans work before retiring is 34. O Ho: p = 34, Ha: P # 34 O Ho: H = 34, Hail # 34 O Ho: H 2 34, Ha: H 34 O Ho: p # 34, Ha: P = 34 O Ho: p 34, Ha: P 34 O Ho: H # 34, Ha: H = 34 Part (b) At most 60% of Americans vote in presidential elections. O Ho: H > 60, Ha: H S 60 O Ho: p > 0.60, Ha: p s 0.60 O Ho: p 0.60 O Ho: H 60 O Ho: H = 60, Ha: H > 60 O Ho: p = 0.60, Ha: p > 0.60 O Ho: H S 60, Ha: H > 60
