tHIS SUBJECT IS Engineering Data Analysis ..... PLEASE HELP... IT IS OKAY IF THERE IS NOSOLUTION MAAM OR SIR...... - IN RETURN I PROMISE TO GIVE HELPFUL RATING DIRECTLY..

Determine the value of c so that the following functions represent joint probability distributions of the random variables X and Y: f(x, y) = cxy, for x = 1, 2, 3: y = 1, 2, 3 O 36 O 1/36 O 1/9 O 6 O 1/18 O 1/6As an example, suppose the random variable X is normally distributed with an unknown mean u. The sample mean is a point estimator of the unknown population mean u. That is, u = X. After the sample has been selected, the numerical value x is the point estimate of J. Thus if x, = 25,x, = 30, x; = 29,x, =31, the point estimate of u is O 28.75 O 26.75 O 30.75 O 32.75
