Question 3 [20] A distribution belongs to the regular 1-parameter exponential family if among other regularity conditions its pdf or pmf has the form: f(x10) = g (x) exp |01 (x) - " (0)1, 0 = 0 C(co, co). Furthermore, for this distribution E[ (X)] = w'(0) and Var[:(X)] = w"(0). Suppose that the daily proportion of new COVID-19 infections in RSA (X') is a random variable with probability density function Ox"-1 if0 > 0 and 0
