Answer:

Step-by-step explanation:

Given that:

The sample size n = 2000

The sample proportion [tex]\hat p[/tex] = 0.14

If [tex]\hat p[/tex] = 0.14, then [tex]\hat q[/tex] = 1 - [tex]\hat p[/tex]

[tex]\hat q[/tex] = 1 - 0.14

[tex]\hat q[/tex] = 0.86

The margin of error = 0.03

Given that the confidence interval level = 99%

The significance level is the value of alpha ∝ = 1 - 0.99

∝ = 0.01
