Medical tests were conducted to learn about drug-resistant tuberculosis. Of 142 cases tested in New Jersey, 9 were found to be d
Andrei [34K]

Answer:

Step-by-step explanation:

Hello!

<u>Sample 1 </u>(New Jersey)

n₁= 142

x₁= 9

^ρ₁=9/142=0.063

<u>Sample 2</u> (Texas)

n₂= 268

x₂= 5

^ρ₂= 5/268 = 0.0186 ≅ 0.019

Since what you need to test is if there is a significant difference between the proportions of drug-resistant cases in both states, the hypothesis are:

H₀: ρ₁-ρ₂=0

H₁: ρ₁-ρ₂≠0

α:0.20

The equation of the statistic is:

Z=<u> (^ρ₁-^ρ₂)-(^ρ₁-^ρ₂) </u>

 √(^ρ(1-ρ)(1/n₁+1/n₂))

Where ^ρ=<u> x₁+x₂ </u>

                  n₁+n₂

The calculated statistic is Z=2.2804

and the p-value= 0.0226

Since the p-value is less than the level of signification, you can reject the null hypothesis. This means that there is enough evidence to conclude that there is a significant difference between the proportion of drug-resistant tuberculosis in both states.
