Is this a matched pairs design for this experiment?
Yes, the company used 24 different vehicles
Yes, both types of tread were randomly assigned to
each vehicle.
No, the vehicles were not put into groups of two
No, the tires with the different types of tread were
not randomly assigned to each vehície,
A tire company wants to determine if tires made with a
new type of tread will last longer than tires made with
the original type of tread. The company has access to
24 different vehicles. Each vehicle will receive four tires
with the new tread and four with the original tread. The
position, front or back, will be randomly determined for
a pair of each type of tread. For example, a vehicle will
have the new type of tread on the front tires and the
original tread on the back tires. After six months, the
pairs of unused tires will be used with the position
switched on the car. The vehicles will be driven for six
more months. At the end of one year, the depths of the
remaining tread will be measured for each fire and the
average differences between the new and original
tread types will be determined. The average
differences will then be used to determine if the new
tread does last longer.

Consider this equation. |y + 6| = 2 what can be concluded of the equation? check all that apply. there will be one solution. there will be two solutions. the solution to –(y + 6) = 2 will be also be a solution to the given absolute value equation. the solution(s) will be the number(s) on the number line 2 units away from –6. the value of y must be positive since the variable is inside absolute value signs.
