Question

In 2016, out of 1956 respondents, 817 said yes, it was the most important. In 2018, out of 1563 respondents, 643 said yes, it was the most important. A) What is the value of P2016, the population proportion of people in 2016 who think for themselves is the most important thing for a child to learn to prepare for life? 1. 0.418 2. 0.415 3. 0.411 4. P2016 is unknown B) Consider the research question: How large is the difference in the proportion of U.S. adults who believed that thinking for themselves was the most important thing for a child to learn to prepare for life between the years 2016 and 2018? What is the symbol of the parameter that should be estimated here? 1. P2016 âˆ’ P2018 2. Î¼2016 âˆ’ Î¼2018 3. XÌ„2016 âˆ’ XÌ„2018 4. Ì‚p2016 - Ì‚p2018 C) The 95% confidence interval for the parameter you identified in Question 3 is (-0.023, 0.043). Based on an alpha level of 0.05, which of the following is a valid conclusion about the population? 1. We can conclude there is no difference between 2016 and 2018 2. We cannot conclude there is a difference between 2016 and 2018 3. There is a difference favoring 2016 4. There is a difference favoring 2018
