Question

Let ? denote the mean reaction time of drivers to brake lights in front of them. A test of ?0:? ≤ 5,?1:? > 5 was performed for several experiments, whose attributes and results are below. Find the ?-value, or bound the ?-value, associated with each of the following.

a. ? = 7, ?0 = 0.94, MUST USE TABLE IN BOOK

b. ? = 12, ?0 = 2.41, MUST USE TABLE IN BOOK

c. ? = 41, ?0 = 3.49, MUST USE EXCEL FUNCTION

d. ? = 13, ?0 = 0.52, MUST USE EXCEL FUNCTION

Answer 1

Ans:

p-value=tdist(to,df,1)

	n	df=n-1	to	p-value
a	7	6	0.94	0.1918
b	12	11	2.41	0.0173
c	41	40	3.49	0.0006
d	13	12	0.52	0.3063
