Researchers recruited more than 750 adults and asked them to wear a new design of shoe. Half of the subjects were randomly assigned to a name-brand shoe, while the other half were assigned to a shoe with no name on the label. On
average, the shoes with the brand name were judged to be more comfortable. Based on this study, is it reasonable to
conclude that including the brand name on the label causes an increase in comfort?
No, association does not imply causation.
No, there was no control group for comparison
No, the adults were not randomly selected from the population of all adults.
Yes, the adults were randomly assigned to the treatments.
Yes, there was a large number of adults involved in the study.

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
