Multiple Choice
The average response time to a bank robbery is about 9 min.A local community wants to improve on this time,so they implement advanced training seminars.They find that the new response time for a sample of 36 police officers is 8 ± 4.2 (M ± SD) min.Test whether this advanced training seminar reduced response time at a .05 level of significance.
A) This advanced training seminar significantly reduced response time, t(35) = 11.43, p < .05.
B) This advanced training seminar significantly reduced response time, t(35) = -1.43, p < .05.
C) This advanced training seminar did not reduce response time, t(35) = -1.43, p > .05.
D) There is not enough information to answer this question.
