Explanation Given info: Consider X be a random variable which follows uniform distribution on the interval 0 and 1. A random sample of 4 observations is drawn from this distribution. Calculation: Uniform distribution: The random variable X said to follow uniform distribution if the probability density function of X is, f ( x i ) = 1 b − a , a < x < b . Joint Probability Density Function: The joint probability density function of the random sample X 1 , X 2 , ... , X n and the parameter θ is f ( x 1 , x 2 , ... , x n , θ ) = ∏ i f ( x i | θ )
