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 rerandomized 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?

hey seth! : )

i’m not 100% sure, but i think it’s b

hope this ya : p

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
