tudy Details for Problems 8 - 11: Randomly selected residents of Oklahoma and Missouri are surveyed. They are asked several questions about their behavior as a result of the COVID-19 pandemic, including whether or not they have been vaccinated. Of the 500 Oklahoma residents sampled, 240 of them have been vaccinated against COVID-19. Of the 650 Missouri residents sampled, 320 of them have been vaccinated against COVID-19. Let Population 1 be Oklahoma residents. The researchers are wanting to determine at the 5% significance level, do the data indicate that the rate of vaccination is different in Oklahoma than it is in Missouri? Screen Shot 2025-08-12 at 8.59.54 AM.png Based on the output, which of the following is the best interpretation of the confidence interval? We are 95% confident that between 4.6% and 7.06% of the sample was vaccinated. We are 95% confident that the true difference in population proportions (Oklahoma - Missouri) is between -0.0706 and 0.046. We are 95% confident that 4.6% to 7.06% more Oklahoma residents are vaccinated than Missouri residents. 95% of the time, Oklahoma will have more vaccinated people than Missouri.
