We investigate if a period of time feels longer or

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, sX= 10.22,n=28
Sample 2 (not bored): X= 9.0, sX= 14.6, n=34
(a) What are H0 and Ha?
(b) Compute tobt
(c) With a = .05, what is tcrit?
(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?
