A parabolic satellite dish reflects signals to the dish’s focal point. An antenna designer analyzed signals transmitted to a satellite dish and obtained the probability density function     for 0 < x < 3.   Where x is the distance (in meters) from the centroid of the dish surface to a reflection point at which a signal arrives. Calculate the value of C.

How is the variance related to the deviations from the mean?

How are objects defined in the context of statistical analysis?

What is a dichotomous variable?
