A new drug claims to reduce the number of eczema breakouts an individual suffers. In a study on the effectiveness of the new drug, 50 subjects were given the new drug and another 50 subjects were given a placebo. At the end of the 6-month study, the group given the new drug reported an average of 1.3 breakouts a month. The group given the placebo reported an average of 4.5 breakouts a month. The data from the study are randomized 10 times. The difference of the means from rerandomization are 1.5, 3.0, 1.8, 1.3, 2.1, 1.9, 2.5, 0.7, 2.1, and 1.9. What is the most appropriate conclusion about the new drug to draw from this information

step-by-step explanation:

i think the correct option is the second option.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
