What superpower do Americans want most? In past years, 10% of Americans chose invisibility as the most
Question:
What superpower do Americans want most? In past years, 10% of Americans chose invisibility as the most desired superpower, based on the Marist poll. Assume this is an accurate representation of all Americans. A group of futurists examines a more recent 2018 Marist poll that found that 12% of those sampled picked invisibility as their desired superpower. The futurists carry out a hypothesis test using a significance level of 0.01, and the result is shown in the StatCrunch output. Based on this, can they conclude that the percentage of all Americans who would pick invisibility as their superpower is still 10%? If not, what conclusion would be appropriate based on these sample data?
