Researchers observed a random sample of drivers and recorded data about their phone usage while driving. The researchers saw 160 of the 800 women using phones, while 300 of the 1200 men were seen using phones. The researchers want to test at the 0.05 level of significance if these results suggest a significant difference between the proportions of men and women that use their phones while driving. Assume that all requirements have been met. Give the null and alternative hypotheses. Find the p-value. Make an initial conclusion based on a mathematical comparison. Then write a formal sentence stating your conclusion in context.

Many traffic accidents are blamed on motorists who are distracted by cell phone use while driving. In a 1999 survey, 30% of adults said that they make phone calls sometimes or frequently while driving alone. A recent random sample of 500 adults showed that 165 of them make phone calls sometimes or frequently while driving alone. At the 1% level of significance, can you conclude that the current proportion of adults who make such phone calls exceeds .3? Identify the...
