Ten healthy adult subjects were asked to walk on a treadmill while connected to monitors. one of two kinds of disturbances was applied during the walk, and the number of steps until adaptation was recorded. each subject experienced both kinds of disturbance, in random order. here are the summary data for these 10 subjects: n mean stdev se mean disturbance a 10 7.320 2.10016 0.66413 disturbance b 10 5.170 1.86073 0.58842 difference a–b 10 2.150 2.68711 0.84974

the correct answer is the second option

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
