Explanation Formula used: Normal probability density function : The function is, f ( x ) = 1 σ 2 π e − ( x − μ ) 2 / 2 σ 2 , σ ≥ 0 . The median of normal probability density function is μ . Uniform probability density function : The function is, f ( x ) = { 1 b − a if a ≤ x ≤ b 0 otherwise . The median of uniform probability function is, m = 1 2 ( a + b ) . Calculation: The probability density functions are f 1 ( x ) = 1 2 π e − x 2 / 2 and f 2 ( x ) = { 0 .4 if − 1.25 ≤ x ≤ 1.25 0 otherwise . Draw the graph of the functions f 1 ( x ) and f 2 ( x ) as shown below in Figure 1. From Figure 1, it is observed that the graph of both the probability density functions f 1 ( x ) and f 2 ( x ) are symmetric with respect to the line x = 0 . Here, the median value is 0 for both the functions. The probability density function f 1 ( x ) = 1 2 π e − x 2 / 2 represents a standard normal distribution

Question 4 Suppose that in a population of twins, males (M) and females (F) are equally likely to occur and that the probability that twins are identical is 0. If twins are not identical, their genders are independent (if they are identical, their genders are the same). (i) Show that, ignoring birth order, P(MM) = P(FF) = (1+0)/4 and P(MF) = (1–0)/2. (ii) Suppose that n twins are sampled. It is found that n₁ are MM, n2 are FF, and në are MF, but it is not known which twins are identical. Find the maximum likelihood estimator of 0.
