Incomplete counterbalancing means that Group of answer choices some participants do not receive all of the treatments. some of the possible orders of treatments are not given. some of the treatments are not given first, some not second, etc. some participants receive the treatments in both the forward and reverse order while others do not.

the first option is the answer.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
