Can it be concluded that the percentage today is greater than 74%? At a=0.05, is he corect? Use the critical value method with tables. Do not round intermediate steps. Part 1 of 5 (a) State the hypotheses and identify the claim. Ho: p= .74 not claim H₁: P> .74 claim This hypothesis test is a one-tailed Alternate Answer: Ho:p=0.74 not claim H₁ :p>0.74 claim This hypothesis test is a one-tailed test. Part: 1/5 Part 2 of 5 ▼test. (b) Find the critical value(s). Round the answer to two decimal places. If there is more than one critical value, separate them with commas. Critical value(s): 0,0....
