Quiz Multiple choice - Statistics Project Example IV. If the process were repeated many times, each time selecting random samples of 500 people aged 20-24 and 450 people aged 25-29 and each time constructing a confidence interval for p1à - p2, 95% of the time the confidence interval limits will contain the true difference between the two population proportions. Assume that you plan to use a significance level ofà à = 0.05 to test the claim that p1à = p2, Use the given sample sizes and numbers of successes to find the pooled estimateà . Round your answer to the nearest thousandth. The table shows the number satisfied in their work in a sample of working adults with a college education and in a sample of working adults without a college education. Assume that you plan to use a significance level ofà à = 0.05 to test the claim thatà à Find the critical value(s) for this hypothesis test. Do the data provide sufficient evidence that a greater proportion of those with a college education are satisfied in their work? Use this approach to find the size of each sample if you want to estimate the difference between the proportions of men and women who plan to vote in the next presidential election. Assume that you want 99% confidence that your error is no more than 0.05. A researcher reports an F-ratio with df= 3, 36 from an independent-measures research study. Based on the df values, how many treatments were compared in the study and what was the total number of subjects participating in the study? A research obtains an F-ratio of F = 4.00 from an independent-measures research study comparing 2 treatment conditions. If the researcher had used an independent-measures t statistic to evaluate the data, what value would be obtained for the t statistic? An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment. For this study, the three samples totals are, T1 = 5, T2 = 10, T3 = 15. What value would be obtained for SS between? An
