14. We investigate if a period of time feels longer or shorter when people are bored compared to when they are not bored. Using independent samples, we obtain these estimates of the time period (in minutes): Sample 1 (bored): X= 14.5, s² = 10.22, n = 28 Sample 2 (not bored): X= 9.0, s = 14.6, n = 34 (a) What are Hō and H₂? (b) Compute tobt (c) With a = .05, what is terit? (d) What should the researcher conclude about this relationship? (e) Compute the confidence interval for the difference between the ?s. (f) Using our two approaches, how important is boredom in determining how quickly time seems to pass?

Transcribed Image Text:14. We investigate if a period of time feels longer or shorter when people are bored compared to
when they are not bored. Using independent samples, we obtain these estimates of the time
period (in minutes):
Sample 1 (bored): X= 14.5, s² = 10.22, n = 28
Sample 2 (not bored): X= 9.0, s² = 14.6, n = 34
(a) What are Ho and H₂? (b) Compute tobt (c) With a = .05, what is terit? (d) What should the
researcher conclude about this relationship? (e) Compute the confidence interval for the
difference between the ?s. (f) Using our two approaches, how important is boredom in
determining how quickly time seems to pass?
