Q7. A business office orders paper supplies from one of three vendors, V₁, V2, or V3.
Orders are to be placed on two successive days, one order per day. Thus, (V2, V3)
might denote that vendor V2 gets the order on the first day and vendor V3 gets the
order on the second day.
(a) List the sample points in this experiment of ordering paper on two successive
days.
(b) Assume the vendors are selected at random each day and assign a probability
to each sample point.
(c) Let A denote the event that the same vendor gets both orders and B the event
that V2 gets at least one order. Find P(A), P(B), P(AUB), and P(An B) by
summing the probabilities of the sample points in these events.

Q5. Extend Theorem 5 (P(AUB) = P(A) + P(B) = P(ANB)), proved in class, to three
events, A, B and C, by finding an expression for P(AUBUC) in terms of the
probabilities of A, B and C, of their pair-wise intersections, and the intersection of
all three events. (Hint: Begin by considering AUB as a single event).

- Can you help me understand this analysis? A 95.7% confidence interval is shown for the intention-to-treat analysis (accounting for alpha spending in interim analyses), and 95% confidence intervals are shown for the other two analyses. The widths of the confidence intervals have not been adjusted for multiplicity. The dashed line indicates the noninferiority margin of 4 percentage points.arrow_forward1 Solve for (x, y, z) in the set of linear, inhomogeneous equations: x-y+2x=5 2x + 3y - z = 4 2x-2y+4z6.arrow_forwardThe sides of a triangular prism base measures 6cm, 8cm and 10cm while it's height is 12cm.

The principal, annual interest rate, and time were all the same; the only difference was that for #5, interest was compounded quarterly. Does the difference in interest earned make sense? Select one of the following statements. a. No, because more money should have been earned through simple interest than compound interest. b. Yes, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. c. No, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. d. Yes, because more money was earned when compounded quarterly. For compound interest you earn interest on interest, not just on the amount of principal.arrow_forward
