### Understanding Cell Phone Use and Crash Risk#### IntroductionStudies have shown that drivers using cell phones while operating motor vehicles increase their risk of an accident. To quantify this risk, the New England Journal of Medicine (January 2, 2014) examined the probability of a crash (or near crash) for both novice and expert drivers using a cell phone.#### Study Overview- **Sample for Novice Drivers:** - **Total Cases:** 371 - **Crashes (or Near Crashes):** 24- **Sample for Expert Drivers:** - **Total Cases:** 1,467 - **Crashes (or Near Crashes):** 67#### Tasks**a) Confidence Interval for Novice Drivers**- **Objective:** Calculate a 93% confidence interval for \( p \), the true crash risk probability for novice drivers, and determine the Margin of Error (ME).- **Answer** - \( ME = \)**b) Confidence Interval for Expert Drivers**- **Objective:** Calculate a 93% confidence interval for \( p \), the true crash risk probability for expert drivers, and determine the Margin of Error (ME).- **Answer** - \( ME = \) This information will help to understand the extent to which cell phone use affects driving safety for different experience levels.

A major company would like to assess the impact of using a professional trainer to conduct a confidence-building workshop with its salespeople. A sample of 16 workers is obtained. Half (n = 8) attend the workshop and the other half (n = 8) serve as a control group. Two weeks later, each of the participants is given a questionnaire measuring the level of self-confidence. The data are as follows: Controls Workshop M = 17.5 M = 22.7 SS = 100 SS = 124 What type of t-test would you have to conduct in this scenario? Are the data sufficient to conclude that the treatment has a significant effect? Use a two-tailed test with α = .05. State the hypothesis, find the critical region, calculate your test statistic, evaluate your hypothesis then calculate the Cohen’s d measure for this scenario. State whether this is a weak, moderate, or strong effect.
