Question
In an acid-base titration, a base or acid is gradually added to the other until they have completely neutralized each other. Let X
and Y denote the milliliters of acid and base needed for equivalence, respectively. Assume X and Y have a bivariate normal
distribution with ox = 5 mL, oy = 2 mL, μx = 120 mL, y = 100 mL, and p = 0.6.
Determine the following:
(a) Covariance between X and Y.
(b) Mean and standard deviation of marginal probability distribution of X.
Mean = i
mL
Standard deviation = i
XIY-102
(c) P(X < 116) =
(d) Mean and variance of conditional probability distribution of X given that Y = 102.
HX|Y=102= i
= | i
(e) P (X < 116 | Y = 102) =
