The image you've uploaded presents a hypothesis testing problem related to the click-through rate of a website. Based on the context and the provided data, the test is likely testing whether the observed sample proportion of 45% differs significantly from the reported population proportion of 34%.

Hypothesis setup:

• The null hypothesis (H₀): The population click-through rate is 34% (p = 0.34).
• The alternative hypothesis (H₁): The population click-through rate is not 34%, which would be denoted as p ≠ 0.34.

Given the choices in the image:

• Correct answer for hypotheses: H₀: p = 0.34 and H₁: p ≠ 0.34 (Option B).

Z-test:

You are asked to calculate the z-statistic, which tests the difference between the sample proportion (0.45) and the null hypothesis proportion (0.34). The formula for the z-statistic is:

$z = \frac{p_{\text{sample}} - p_{\text{null}}}{\sqrt{\frac{p_{\text{null}} (1 - p_{\text{null}})}{n}}}$

Where:

• $p_{\text{sample}} = 0.45$
• $p_{\text{null}} = 0.34$
• $n = 545$

Let's compute the z-statistic.

Do you need me to calculate the z-statistic and p-value for you, or would you like more clarification?
