That is, Pr ( X = 1 , Y = 14 ) = 0.02 , and so forth. Calculate the probability distribution, mean, and variance of Y. Calculate the probability distribution, mean, and variance of Y given X = 8 . Calculate the covariance and correlation between X and Y.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

answer: i feel you honey.

step-by-step explanation:

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
