Question
A random sample of 180 men indicated that 50 were smokers, and a random sample of 150 women surveyed indicated that 39 smoked. Construct a 98% confidence interval for the true difference in proportions of male and female smokers.
The image presents a statistical exercise focused on calculating proportions and their complements for a given dataset involving men and women. Here's a structured transcription suited for an educational website:

---

**c) Find the value of each statistic.**

**Express as a decimal rounded to four decimal places**

- **Proportion One (Men):**
  - Select an answer from a dropdown menu
  - An input box follows to write the calculated proportion
  
  *(Calculate using a TI-84 calculator)*

- **Proportion Two (Women):**
  - Select an answer from a dropdown menu
  - An input box follows to write the calculated proportion
  
  *(Calculate using a TI-84 calculator)*

\[ \hat{q}_1 = 1 - \hat{p}_1 = 1 - \text{(Men's Proportion)} = \]
  - Input box for calculation related to men

\[ \hat{q}_2 = 1 - \hat{p}_2 = 1 - \text{(Women's Proportion)} = \]
  - Input box for calculation related to women

- **Sample Size One (Men):**
  - Select an answer from a dropdown menu
  - An input box follows to write the sample size

- **Sample Size Two (Women):**
  - Select an answer from a dropdown menu
  - An input box follows to write the sample size

**Round answer(s) to two decimal places**

- \( z (\alpha/2) \): 
  - Select an answer from a dropdown menu
  - Multiple input boxes follow, suggesting multiple calculations or values needed

- Second line with similar setup for another z-score calculation related to \( \alpha/2 \).
