Study 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? The researchers conduct the two-sample hypothesis test and calculate a z-statistic of -0.41 and a p-value of 0.6790. Assuming a level of significance of 0.05, what is the correct conclusion for the hypothesis test? Since the p-value (0.6790) is greater than the significance level (0.05), we fail to reject the null hypothesis and conclude that the vaccination rates are not significantly different in Oklahoma and Missouri. Since the p-value (0.6790) is greater than the significance level (0.05), we reject the null hypothesis and conclude that the vaccination rates are different in Oklahoma and Missouri. Since the z-statistic is negative, we reject the null hypothesis and conclude that the vaccination rate is higher in Oklahoma than in Missouri. Since the p-value (0.6790) is greater than 0.48 (the sample proportion for p1), we reject the n
