3. (a) Suppose that ri,...,In are a random sample having probability density function C: a Here α is restricted to be positive. Determine the MLE of α (b) Suppose that ri, , Vn are a random sample from a geometric distribution ㄨㄧ Here the parameter 0 < θ < I. Determine the MLE of θ and show carefully that it is an MLE: it does not suffice to solve the score equation.

10 points (bonus) A propositional formula on n variables, P(ri,2,... ,Tn) is satisfiable if there exists an assignment of truth values (true or false) to its variables such that it evaluates to true. (a) Give an algorithm (pseudocode) that, given a formula P determines if it is satisfiable or not. Analyze your algorithm. b) Suppose that we are given a free" algorithm A that, given P and a partial assignment of truth values (that is, some variables are set to...

Let x1,..., Tn be a variable measured for units in a sample with sample variance given by s - a-2)2 T where r r, is the mean of the sample. Let u denote the mean of the population from which 2-1 the sample came. Let yi -xi - 7, for i -1,...,n. How do the values of sz and sy compare to s2 and sz? Prove your result.

3. Let Tn(x) be the degree n Chebyshev polynomial. Evaluate Tn (0.5) for 2 <n < 10, by applying the three-term recurrence directly with x = 0.5, starting with T.(0.5) = 1 and Ti(0.5) = 0.5.

One factory claims that its remote control carts last an average of 320 hours. To verify this average, a sample of 15 carts is taken. If the calculated value falls within a symmetrical range from the 90% average, the factory is satisfied. What conclusion would the company obtain according to this sample? The sample were the following data: 320, 321, 311, 313, 310, 300, 302, 312, 310, 275, 310, 287, 293, 300, 295
