Question

When it comes to technology's influence on America's young adults, reading is not dead-at least not the news. Overall, more Americans prefer to watch their news than to read it or listen to it. But does that preference vary by age? To explore this question, we took a large random sample of young American adults (18-34 years old) and a large random sample of older American adults (50+ years old) and asked each if they prefer to watch the news versus reading the news. Using the sample results, we constructed a 99% confidence interval for the difference n population pro or on of young American adults who prefer to watch the news versus reading the news less the population proportion of older American adults who prefer to watch the news versus reading the news to be between (-0.005, 0.258) Question 2 Subquestions 2.a Select the option that best completes the following interpretation statement: 1 point(s) We estimate the values of the difference in the proportions vary by roughly from the difference in the proportions, on average. population, 0.1315, sample population, 0.0510, sample population, 0.1265, sample sample, 0.1315,population sample, 0.0510, population sample, 0.1265, population

Explanation / Answer

The lower Limit : (p1 - p2) - ME = -0.005 and the Upper Limit: (p1 - p2) + ME = 0.258

Adding we get 2*(p1 - p2) = -0.005 + 0.258 = 0.253

Therefore p1 - p2 = 0.1265

Option 3 is the correct answer: Population, 0.1265, sample
