Question

When possible, the best way to establish that an observed association is the result of a cause and effect relation is by means of the least squares regression line the correlation coefficient a two-way table a well-designed experiment. Two variables are said to be confounded it one cannot separate their effects on a response variable they are highly correlated. they do not have a normal distribution. one of them is a placebo. M&M;'s come in a variety of colors such as red, yellow, orange, blue, green brown [No points without explanation or justification]. If you draw one (1) M&M; are the events of getting a red one and getting green one disjoint, independent or neither? Explain If you draw two (2) M&M;'s one after the other are the events of getting red M&M; on the first selection and a red M&M; on the second selection independent or neither? Explain?

Explanation / Answer

e)

Two variables are said to be counfounded if their effect on response variable can distribuish one another.

So here correct option is 1)

a)

M&M comes variaety of colours.

if you draw red and green so both are independent .

because they are not depend on each other.

P(red and green ) =P( red) * P( green )

b)

If you draw two colours first you draw red and second also you draw red both are dependent because P( red ) is change in second event .

Not independent and nor disjoint correct option is neither.
