- What is the positive t-value for a confidence interval for the population mean with a sample size of 30 at a 90% confidence level? Express with 3 decimalsA survey by the society of Human Resource Management asked 350 job seekers why employees change jobs so frequently. The answer selected most (126 times) was "higher compensation elsewhere" as the reason for changing jobs. Then the 95% confidence interval estimate for the population proportion of job seekers who would select "higher compensation elsewhere" as the reason for changing jobs is approximately.The distance a basketball player runs during a game is one of the many variables used for assessing the performance of the players. 72 players are followed for a game each and the average distance ran by them is found to be 3494 meters (m) with a standard deviation of 133 m. Then the lower limit for the 95% confidence interval for the true mean is and the upper limit is ious NEXT Save
- We would like to compute a 95% confidence interval for the difference of proportions of men and women who are frequent binge drinkers. Of 534 males, 26% admitted to frequent binge drinking as opposed to 20.6% of 847 women. The 95% confidence interval for the difference of proportions (proportion of males - proportion of females) is (0.0179, 0.1001). Based on this confidence interval, can we conclude that men are more likely to frequently binge drink than women?
