In a political campaign, one candidate has a poll taken at random from the voting population. The results of poll are that 301 out of 400 voters favor the candidate. Let P be the fraction of the voting population that favors the candidate. 0.05 (i) Test Ho: p= 0.8 against H₁ : p < 0.8 at significance level a = (ii) Test Ho: p = 0.8 against H₁ : p < 0.8 at significance level a = 0.01. (iii) Compute the associated p-value. (iv) What is the smallest significance level a for which we can reject Ho: p = 0.8 in favor of H₁ : p < 0.8?
