5. Suppose XExp(A). (a) [5 pts) Show that E(X) 1/A. Hint: You can directly use the definition and properties of a gamma function.] (b) [5 pts] Prove that P(X > t +s | X > s) = P(X > t) for s, t > 0, [Hint: You can directly use the tail probablity P(X >) e for 0.]
please show work. will rate.
Two Step Reaction -> CooH 1. What reagent(s) would you use in the first step? 2. Draw the proposed intermediate product 3. What reagent(s) would you use in the second step? 4. Draw the complete mechanism from the starting reactant to the end product

thank you!
If oỉ > oộ, then R is a decreasing function of 21_1 (– u). So we should reject Ho if 1-1 (di – u)? is sufficiently large. 3 (ti – )>C* i=1 The rejection threshold depends on the size of the test. In this example, the test statistic can be shown to be a scaled Chi-square distributed random variable and an exact critical value can be obtained. under...
can you solve and show work if possible
