Question

In 2009 news organizations reported that 47% of U.S. adults favored providing a legal way for illegal immigrants already in the U.S. to become citizens. In 2010, the percentage with this opinion rose to 50%. Suppose that a current poll of 100 randomly selected U.S. adults shows this percentage is higher than 50% this year. A researcher conducts a hypothesis test with the data from the current poll. She finds that the increase this year is not statistically significant. What conclusion can we draw

Answer 1

The exercise tells us about a process that has been submitted to public opinion and has obtained different results in the population, with different variations regarding the legalization of immigrants in the United States. This time, a survey with 100 adults obtained at random is being tested. and it has a result, finding significant changes with respect to the first event, however we must conclude that the sample size is too small to detect a statistically significant increase, due to the value of people surveyed, to have a more impactful result there should be more people surveyed
