Among 310 infants using bednets, 12 developed malaria. Among 275 infants not using bednets, 27 developed malaria. Use a 0.01 significance level to test the claim that the incidence of malaria is lower for infants using bednets. a. Test the claim using a hypothesis test. b. Test the claim by constructing an appropriate confidence interval. c. Based on the results, do the bednets appear to be effective? a. What are the null and alternative hypotheses? Let the infants using bednets be sample 1 and let the infants not using bednets be sample 2. Choose the correct hypotheses below. A. $H_0: P_1 \le P_2$ $H_1: P_1 > P_2$ B. $H_0: P_1 = P_2$ $H_1: P_1 > P_2$ C. $H_0: P_1 = P_2$ $H_1: P_1 < P_2$ D. $H_0: P_1 \ne P_2$ $H_1: P_1 = P_2$ E. $H_0: P_1 = P_2$ $H_1: P_1 \ne P_2$ F. $H_0: P_1 \ge P_2$ $H_1: P_1 < P_2$ Identify the test statistic.

Suppose you could travel back in time to day zero t = 0 and invest $1000 in these two companies. Your stock portfolio can be defined as: X1 p1[0] + X2 p2[0] = 1000 where X1 and X2 correspond to the number of shares of each company. Find X1 and X2 such that the value of your investment at time T-1 is $2000. Note: X1 and X2 can be negative. Negative X1 means you are shortselling the Intel stocks, and negative X2 means you are shortstelling the Johnson & Johnson stock

17.5 Homework 2, P1: Date Calculator Prompt the user to enter the month and day of the year (1 for January, 2 for February..) Prompt the user to enter a period of time in days Print the date after the period entered by the user has passed. For simplicity, assume that each month has 30 days except for February that always counts for 28 days. Sample output: Enter the month and day: 3 5 Enter the days forward: 50 After 50 days, the date of 3/5 will be 4/25 Test cases: (Month Day Period New Date) (3, 5, 50, 4/25), (1, 1, 15, 1/16), (1, 1, 33, 2/4), (1, 1, 60, 3/3), (1, 1, 370, 1/13)
