Suppose the force of mortality x = 1/20 for all ages x. A life table is being constructed with starting population lo Rounding to nearest integer values, which one of the following is true? a. = 950,12 = 900,13 = 850. O b. 1 = : 951, 12 = 905,13 = 861. c. 1 = 980, 12 = 960, 13 = 940. O d. 1 = 905,12 = 819,13 = 741. = 1000. Consider the life table lo = 100, = 90, 12 = 80, 13: = 70, .../10 = 0. Which one of the following is true? a. qx = 11 for 0 x 1. 10 b. The force of mortality is constant for 0 x < 10. c. The force of mortality x for 0 x < 10, is a decreasing function of x. d. The force of mortality x for 0 x < 10, is an increasing function of x. Consider the same life table as question 3, 10 future lifetime at birth (x = 0)? = 100, = 90, 12 = 80, 13 = = 70, ... 10 = = 0. What is the expected curtate a. 5.5 b. 5.0 . 4.5 O d. 4.0
