Estimation and Interval Estimation Exercise State the point estimate for each of the following examples. 1. A researcher records the following values: 12, 8, 10, 12, 17, 11, and 14. 2. The time it takes to complete a behavioral task is 32 2.4 (M SEM) s. 3. Researchers measure scores in two related samples. Participants in Sample 1 scored 8.2 points and in Sample 2 scored 4.6 points. 4. Distance that participants stood from an attractive confederate was closer than predicted, 95% CI 14 to 26. State the interval estimate that contains more possible values of the population mean (precision) for each of the following examples. 5. A 90% CI or a 95% CI for the same data. 6. An 80% CI for a distribution with 12 1.2 (M M) or 12 1.2 (M sm). 7. A 99% CI for a distribution with 18 3.0 (M s) or 18 3.0 (M SM-M). The sample size is 40 for each distribution. 8. A 95% CI for a distribution with 103 14.0 (M SMD) or 9814.0 (M SMD). The sample size is the same for each distribution. State the interval estimate that is associated with the largest certainty. 9. A 90% CI or a 95% CI for any data. 10. A 90% CI for a distribution with 9.7 0.8 (M ) or a 90% CI for a distribution with 200.8 (M). 11. An 80% CI for a z-test or an 80% CI for a t-test. 12. A 99% CI for a distribution with SM = 3.2 or a 95% CI for a distribution with SM = 0.2.
