**Question (a):** What is the sample statistic?- 0.2238 (selected)- 0.15- 0.0857- 0.007**Question (b):** Which symbol is used for the statistic in this problem?- π- μ- p̂- x̄**Question (c):** Which hypotheses are being tested?- H₀: μ = 0.15 Hₐ: μ ≠ 0.15- H₀: π = 0.0857 Hₐ: π ≠ 0.0857- H₀: π = 0.15 Hₐ: π ≠ 0.15- H₀: π = 0.007 **Simulation of Proportion of Successes in Binomial Distribution****Parameters:**- **Probability of success (π):** 0.15- **Sample size (n):** 210- **Number of samples:** 1000**Options:**- Animate the simulation process.- Focus on the Proportion of successes.**Inputs:**- **As extreme as**: ≤ 0.0857 (threshold for comparison)- Calculated **Proportion of samples**: (6 + 1) / 1000 = 0.0070**Statistical Methods Selected:**- Two-sided test for proportion values.- Use of Exact Binomial distribution.- Normal Approximation method.**Graph Description:**The graph depicts the distribution of the proportion of successes across 1000 samples. The x-axis represents the "Proportion of successes," ranging from approximately 0.08 to 0.23. The y-axis shows the frequency of samples, with a peak frequency of around 90.- A normal distribution curve (in blue) overlays the frequency bars.- Two red vertical lines indicate the cutoff points used in the analysis: - Left line at 0.0857 - Right line at 0.2238- The area under the curve for proportions less than or equal to 0.0857 is highlighted with a red label showing 0.0070, representing the proportion of samples as calculated.**Additional Features:**- Options to show previous results or enable sliders for dynamic adjustments.

A study of seat belt users and nonusers yielded the randomly selected sample data summarized in the accompanying table. Use a 0.05 significance level to test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke are less concerned about their health and safety and are therefore less inclined to wear seat belts. Is this theory supported by the sample data?
