**Hypothesis Testing on Cat Ownership**

**Objective:**
Test the claim that the proportion of men who own cats is smaller than the proportion of women who own cats at the 0.025 significance level.

**Hypotheses:**

- **Null Hypothesis (H₀):** pₘ = pₜ   (The proportion of men who own cats is equal to the proportion of women.)
- **Alternative Hypothesis (H₁):** pₘ < pₜ  (The proportion of men who own cats is smaller than the proportion of women.)

**Test Type:**
- One-tailed (left-tailed)

**Data Summary:**

- **Men:** 
  - Sample size = 80
  - Proportion owning cats = 35%

- **Women:** 
  - Sample size = 40
  - Proportion owning cats = 45%

**Statistical Analysis:**

- **Test Statistic:** Calculated value (rounded to 2 decimal places)
- **P-value:** Calculated value (rounded to 2 decimal places)

**Decision Rule:**
- **Reject the null hypothesis:** If the p-value is less than the significance level (0.025).
- **Fail to reject the null hypothesis:** If the p-value is greater than the significance level (0.025).

Choose the appropriate hypothesis and test type to perform the analysis. Calculate the test statistic and p-value accordingly, and then decide whether you can reject the null hypothesis based on the calculated p-value.
