Confidence interval questions For the following numerical questions on this page, report the answers to the nearest 0.001. Consider the sample: 23,25,20,27,28,24,27 ,22,28,31,22,23,21,29 Q12. What is the standard error for this sample? SE = 77?7 Q13-14. Provide the values for the lower and upper values for Lower value = ??7? the 95% confidence interval of the population mean. Upper value = ??? Q15. If someone claimed that the mean of the population this sample came from was 27, what would you think about that claim? Your choices: () There's no reason to decide the claim isn't true since that value is outside the 95% confidence interval. () There's no reason to decide the claim isn't true since that value is within the 95% confidence interval. () The claim is unlikely to be true since that value is outside the 95% confidence interval. () The claim is unlikely to be true since that value is within the 95% confidence interval. Consider the sample: 27,30,37,34,28,31,33,26,34,32, 28, 32 Q16-17. Provide the values for the lower and upper values for Lower value = ??7? the 95% confidence interval of the population mean. Upper value = ??? Q18. If someone claimed that the mean of the population this sample came from was 33, what would you think about that claim? Your choices: () There's no reason to decide the claim isn't true since that value is outside the 95% confidence interval.
