Answer 1

Answer:n

Step-by-step explanation:n

Answer 2

Given

p₁ = 30%

p₂ = 25%

To Find:

evaluate Hypothesis ​

Explanation:

p₁ = 0.3

p₂ = 0.25

So that p₁ -p₂ = 0.3 - 0.25

                      = 0.05

e² = (p₁q₁)n₁ + (p₂q₂)n₂

   = 0.3×(0.7/1200) + 0.25×(0.75/900)

e = 0.0195

z = (p₁ -p₂)e

z = 0.05/0.0195

z = 2.5
