You may need to use the appropriate appendix table or technology to answer this question. A certain financial services company uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time. A recent sample of 1,000 adults showed 410 indicating that their financial security was more than fair. Suppose that just a year before, a sample of 1,200 adults showed 420 indicating that their financial security was more than fair. (a) (b) (c) State the hypotheses that can be used to test for a significant difference between the population proportions for the two years. (Let p security more than fair. Enter ! for as needed.) Conduct the hypothesis test and compute the p-value. At a 0.05 level of significance, what is your conclusion? Find the value of the test statistic. (Use p 1 02. Round your answer to two decimal places.) Find the p-value. (Round your answer to four decimal places.) p-value State your conclusion. population proportion most recently saying financial security more than fair and p population proportion from the year before saying financial O Reject H . There is insufficient evidence to conclude the population proportions are not equal. The data do not suggest that there has been a change in the population proportion saying that their financial security is more than fair. O Reject H . There is sufficient evidence to conclude the population proportions are not equal. The data suggest that there has been a change in the population proportion saying that their financial security is more than fair. O Do not reject H . There is insufficient evidence to conclude the population proportions are not equal. The data do not suggest that there has been a change in the population proportion saying that their financial security is more than fair. O Do not reject H . There is sufficient evidence to conclude the population proportions are not equal. The data suggest that there has been a change in the population proportion saying that their financial security is more than fair. What is the confidence interval estimate of the difference between the two population proportions? (Round your answers to four decimal places.) What is your conclusion? The confidence interval v zero, so we can be confident that the population proportion of adults saying that their financial security is more than fair
