Hey there!
"What ratio forms a proportion with
?"
-
(for the decimal)
But in order for you to solve this particular equation you'd have to go in with two (like multiplying by two)
Your result: ![\boxed{Answer: B. \frac{7}{21} }](https://tex.z-dn.net/?f=%5Cboxed%7BAnswer%3A%20B.%20%5Cfrac%7B7%7D%7B21%7D%20%7D)
Good luck on your assignment and enjoy your day!

Answer:
![Z_{H0} =1.79](https://tex.z-dn.net/?f=Z_%7BH0%7D%20%3D1.79)
p-value: 0.0367
Decision: Reject H₀
Step-by-step explanation:
Hello!
Hypothesis to test:
H₀:ρ₁-ρ₂=0
H₁:ρ₁-ρ₂>0
The statistic to use to test the difference between two population proportions is the approximation of Z
Z=<u> (^ρ₁-^ρ₂)-(ρ₁-ρ₂) </u> ≈N(0;1)
√ (<u>^ρ₁(1-^ρ₁))/n₁)+(^ρ₂(1-^ρ₂)/n₂))</u>
Z=<u> (0.28-0.15)-0 </u>= 1.79
√ (<u>0.28(1-0.28)/200)+(0.15(1-0.15)/300)</u>
p-value
Remember: The p-value is defined as the probability corresponding to the calculated statistic if possible under the null hypothesis (i.e. the probability of obtaining a value as extreme as the value of the statistic under the null hypothesis).
P(Z>1.79)= 0.0367
Conclusion:
Comparing the p-value against the significance level, you can decide to reject the null hypothesis.
I hope you have a SUPER day!
