17.18 4S overall mortality. The 4S study introduced in Exercise 17.17 also tallied deaths due to any cause. The treatment group experienced 182 deaths (n1 = 2221) and the control group experienced 256 deaths (n2 = 2223). Compare the mortality experience in the two groups in the form of a relative risk and 95% confidence interval.
Using the results below: M1 = 18.57, M2 = 18.33, SM1−M2 = 0.97, tcv = 1.997 1. Calculate a 95% confidence interval estimating the true difference between the population means. Write the final answer in brackets [x.xx, x.xx]. 2. Based on your answer, explain whether there is a significant difference between the two population means. What about your answer tells you whether there is a significant difference or not?
The results below are based on data collected on campus as part of a student project for an introductory statistics class at UF. If there is more than one group/treatment, the first group mentioned is group 1. Data was collected to compare the proportion of "Greeks" and non-"Greeks" who voted for Obama in 2012. "Greeks" are students who belong to a fraternity or sorority. The p-value was 0.00, and the 95% confidence interval was ( -0.534, -0.202). This problem is about _ two independent proportions ? _ The sign of the alternative hypothesis should be _ not = ? _ Based on the p-value we can _ reject the Ho _ at alpha = 0.05. At which alpha levels could we Reject Ho? _ all of usual alpha levels _ Are the results statistically significant at alpha=0.01? _ yes _ We have _ very strong evidence _ to say that the proportion of "Greeks" who voted for Obama is different from the proportion of non-"Greeks". We are 95% confident that the proportion of "Greeks" who…
A sample of size 25 was taken from a very large population. Sample statistics, and s, were used to find that the 80% confidence interval was (159.046, 166.954). S =
According to a study completed in 2006 by Pew Internet, 42% of all Americans had a broadband Internet connection at home. This same statistics student wanted to see if this percentage is different for students at his university. Ho: p = 0.42 Ha: p ≠ 0.42 Based upon the data the student collected, a 95% confidence interval for p was found to be: (0.439, 0.457). At the 0.05 level of significance, which conclusion can be made? a. The student should reject the null hypothesis, because 0.42 is a possible value for p given the data collected. b. The student should not reject the null hypothesis, because 0.42 is not a possible value for p given the data collected. c. The student should reject the null hypothesis, because 0.42 is not a possible value for p given the data collected. d. The student should not reject the null hypothesis, because 0.42 is a possible value for p given the data collected.
Use Table V in Appendix A to determine the t-percentile that is required to construct each of the following two-sided confidence intervals: (Express your answers to 3 decimal places.) Confidence level = 95 %, degrees of freedom = 11 , Confidence level = 95% , degrees of freedom = 14 Confidence level = 99 %, degrees of freedom = 12 Confidence level = 99% , degrees of freedom = 10
Suppose we are able to use a normal model. In order to construct a 99% Confidence Interval, we have to find the margin of error (ME), and we can use the following formula: 2.579*SE, where SE is computed with the image that's attached to this problem. Using SE = 0.049, find ME for the 99% Confidence Interval. Round your answer to 3 decimal places.
A psychologist is studying the effects of lack of sleep on the performance of various perceptual-motor tasks. After a given period of sleep deprivation, a measurement of reaction time to an auditory stimulus was taken for each of 36 adult male subjects. The reaction times (in seconds) are summarized as follows:x = 1.82, S=0.22. Find a 99% confidence interval for the mean reaction time for sleep-deprived male subject
