Question

The average response time to a bank robbery is about 9 minutes.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)minutes.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.
