A researcher claims that exactly 40% of all adults in the U.S. use their cell phone for most of their online browsing. You believe that the true proportion is different. To test this, you take a simple random sample of 200 adults in the U.S and find that 39% of them use their phone for most of their online browsing. Test at 5% significance. Round to the fourth as needed What's the minimum population size required? How many successes were there? H0H0: HAHA: Test Statistic: P-value: Did something significant happen? Select the Decision Rule: There enough evidence to conclude Build a 95% confidence interval and decide if you can conclude the same. Use your calculator to do this and round to the fourth decimal place. (,) Can we conclude the same as our Hypothesis Test? because the true proportion of U.S. adults that use their cell phones for most of their online browsing
