An internet company conducts a global consumer survey to multinational companies understand different consumer attitudes throughout the world. within 30 countries, the researchers interview 1000 people aged 13-65. their sample are designed so that they get 500 makes and 500 females in each country.
a.) are they using simple random sample?
b.) what kind of design do you think they are using?

answer: your answer is c

step-by-step explanation:

33/100 is what i got

one way is to plot 2 points and connect them which is what the answer choices seem to be doing

it seems to be using the y intercept and the slope

y=mx+b, m=slope, b=y-intercept (where the line hits the y axis)

slope=rise/run

y-intercept is where the line croses the y axis which is the y value where x=0

you seem to have given the wrong slope (you didn't put a number in front of te x, it should be 2/3 or 3/2 looking at the answer options)

y=? x-1

m=? because of your fault

b=-1

so it has a slope of ? and y intercept of -1, meaning it pases through (0,-1)

so draw point (0,-1) (so answer is one of the first 2 option)

if slope is 2/3, then go up 2 and right 3 then draw line through those 2 points

if slope is 3/2, then go up 3 and right 2 then draw line through those 2 points
