How would you report the results? The derived t = 0.74 was not significant at p = .05 with df = 19. Therefore, Ho was not rejected, and it was concluded that the mean number of errors for subjects after 8 hours of sleep deprivation (2.02) was not different than the mean number of errors after 24 hours of sleep deprivation (13.90), t(19) = 0.74, p > .05. In terms of the research question, it appears that sleep deprivation did not increase the number of errors in this sample. The derived t = 3.30 was significant at p .05 with df = 18. Therefore, Ho was rejected, and it was concluded that the mean number of errors for subjects after 24 hours of sleep deprivation (2.02) was different than the mean number of errors after 8 hours of sleep deprivation (2.12), t(18) = 3.30, p < .05. In terms of the research question, it appears that sleep was effective in reducing number of errors in this sample. O The derived t = -9.70 was significant at p = .05 with df = 19. Therefore, Ho was rejected, and it was concluded that the mean number of errors for subjects after 24 hours of sleep deprivation (13.90) was significantly higher than the mean number of errors after 8 hours of sleep deprivation (6.75), t(19) = -9.70, p < .001. In terms of the research question, it appears that sleep deprivation increased the number of errors in this sample. O The derived t = -7.15 was significant at p .05 with df 1. Therefore, Ho was rejected, and it was concluded that the mean number of errors for subjects after 8 hours of sleep deprivation (6.75) was significantly lower than the mean number of errors after 24 hours of sleep deprivation (13.90), t(1) = -7.15, p < .000. In terms of the research question, it appears that sleep was effective in reducing number of errors in this sample. O The derived t = 0.74 was significant at p = .05 with df = 20. Therefore, Ho was rejected, and it was concluded that the mean number of errors for subjects after 8 hours of sleep deprivation (2.02) was significantly lower than the mean number of errors after 24 hours of sleep deprivation (2.12), t(20) = 0.74, p<.01. In terms of the research question, it appears that sleep was effective in reducing number of errors in this sample.
