The mayor of a town has proposed a plan for the construction of a new bridge. A political study took a sample of 1200 voters in
Kipish [7]

Answer: H_0:p\leq0.53

H_a:p>0.53

Step-by-step explanation:

Claim :  A a political strategist wants to test the claim that the percentage of residents who favor construction is more than 53%.

Let 'p' be the percentage of residents who favor construction .

Claim : p> 0.53

We know that the null hypothesis has equal sign.

Therefore , the null hypothesis for the given situation will be opposite to the given claim will be :-

H_0:p\leq0.53

And the alternative hypothesis must be :-

H_a:p>0.53

Thus, the null hypothesis and the alternative hypothesis for this test :

H_0:p\leq0.53

H_a:p>0.53
