Answer:
5.13
Step-by-step explanation:
Number of sampled workers= n= 1000
Percentage of residents favouring construction= p' = 60% = 60/100= 0.6.
Testing the claim that the percentage of people favouring the construction is more than 56%= p= 56/100 = 0.56.
To calculate the test statistics we use the formula below;
Test statistics= √n (p' - p)/ √[p×(1-p)] -----------(1).
Substituting the value into equation (1) above, we have;
Test statistics= √1000 (0.6-0.56) / √[0.56×(1-0.56)]
Test statistics= (31.62)(0.04) / √0.5(0.44) = 1.2648/ 0.2464
Test statistics= 5.13312
= 5.13 (to 2 decimal places)
the answer for this question is ( d)
