Required information A recording tape passes over the 20-mm-radius drive drum B and under the idler drum C. A $T_A$ D M Knowing that the coefficients of friction between the tape and the drums are $\mu_s$ = 0.40 and $\mu_k$ = 0.30 and that drum C is free to rotate, determine the smallest allowable value of P if slipping of the tape on drum B is not to occur. Given: M = 0.5 N-m. (Round the final answer to three decimal places.) The smallest allowable value of P if slipping of the tape on drum B is not to occur is N.

For the following instrumental variables (IV) regression model Yt = ?T xt + ut, xt = ?T wt + vt, (4) where E(ut|xt) ? 0 and E(ut|wt) = 0. Here, it is assumed that wt is l × 1 and xt is k × 1 with l ? k for the identification. If l > k, model (4) is over-identified. (a) Please derive the IV estimator for ?, denoted by ??IV. (c) Show all steps on tests of over-identifying restrictions and the DWH test for model (4). Durbin-Wu- Haussman test
Events A, B and C are disjoint. For the following event probabilities: P(A)=0.12, P(B)=0.64, P(C)=0.24, P(D|A)=0.100, P(D|B)=0.086, P(D|C)=0.103, calculate P(B|D). Your answer: 0.760 0.407 0.771 0.862 0.600 0.297 0.003 0.323 0.780 0.846
