Question 9 < > Part 1 of 2 In a randomly selected sample of 1135 individuals in a state, 779 were in favor of expanding background checks for gun ownership. Construct a 90% confidence interval for the proportion of all individuals in favor of expanding background checks in this state. a) Round to 4 decimal places, if needed. Check requirements: b) Is this a random sample or a randomized experiment? O no yes C) Are the observations independent? Check this by using n < 0.05N. 0.05N What does this tell us the required population size is? Round to 1 decimal place, if needed. N Note, the smallest population of any U.S. state is about 580,000 people. This means that The observations are independent because the sample size is less than 5% of the population size, i.e. n < 0.05N It is impossible to tell whether the observations are independent or not with the given information. The observations are NOT independent because the sample size is NOT less than 5% of the population size, en 0.05 N
