Use likelihood funtion

Let X be the uniform random variable on the interval [0, 9] with unknown parameter 6, and let 3:1, . . . ,zvn be samples values for X. (a) (3 points) Compute the likelihood function for this random variable. (b) (3 points) By using the method of maximum likelihood estimate, compute the estimator 9 for the unknown parameter 6. (c) (3 points) Is 9' an unbiased estimator? Why or why not? (Hint: It might help to use the pdf of ordered statistics from Section 6.3) 9 Pdf of order statistics Theorem 3. Let X1, ..., Xn be independent, identical continuous random variables. Then the pdf of Yk (for 1
