Question 3 A distribution belongs to the regular 1-parameter exponential family if among other regularity [20] conditions its pdf or pmf has the form: S (x10) = 8 (x) exp 101 (x) - 4 (0)1. Bcec (00,00). F12 Furthermore, for this distribution EL/ (X)] = y'(0) and Var|: (X)] = "(0). B Suppose that the daily proportion of new COVID-19 infections in RSA (X) is a random variable with probability density function Cter 2.7. 346 Example 4.2.1 0x0-1 ife > 0 and 0
