a) Let Z be the time at which the last student finishes. Show that Z has a distribution function FZ (z) given by [1 exp( z] . b) Let T1 be the time at which the first student leaves. Show that the probability density of T1 is given by n e n t . For each i, 2  i  n, let Ti be the interval from the departure of the i 1st student to that of the ith. Show that the density of each Ti is exponentia...

(FP1) The exclusive or operation, denoted by ⊕ and sometimes known as XOR, is defined so that P ⊕Q is true iff P is true or Q is true, but not both. Prove (through a truth table, or otherwise) that for any statements P,Q,R: (a) ((P ⊕Q)⊕R)⇔ (P ⊕ (Q⊕R)) (b) (P ∧ (Q⊕R))⇔ ((P ∧Q)⊕ (P ∧R)) Answer. One could show both sentences were true through a truth table, either through showing the entire senten...

Forty subjects were randomly divided into five groups of eight subjects in each group. A different training program was assigned to each group. After 2 months, the improvement in endurance was recorded for each subject. A one-way ANOVA is used to compare the five tr...

Answer: For the preferences to be the same, it must be that vi = aiui+bi for some ai and bi where ai is positive and ui and vi are the utility functions of i in the left and the right game, respectively. Since u1 (b,M) = 0 and v1 (b,M) = 3, we must have b1 = 3 (Row player is 1 and the column player is 2.) Since u1 (c,M) = 1 and v1 (c,M) = 5, we then have a1 = 2. But v1 (a, L) = 12 6 · 2+3 = 2 ....
