Answer:
Standard error = 0.028
Step-by-step explanation:
Standard error of the mean = √x(N-x)/N3 = 0.028
Standard error is 0.028
If you need further answer, see below
α = (1-CL)/2 = 0.025
Standard normal deviate for α = Zα = 1.960
Proportion of positive results = P = x/N = 0.720
Lower bound = P - (Zα*SEM) = 0.664
Upper bound = P + (Zα*SEM) = 0.776
95% Confidence interval is 0.664 to 0.776
