2 ) if (d) a(y0) = n(cid:22)y+y0 y0 > y( n+1. 2 ) so it does not change as y0 ! 1. 2. (a) both are multiplied by jbj (c) as y0 increases to in(cid:133)nity, so does the sample stan- dard deviation s (d) once y0 is larger than q(:75); it has no e ect on the interquartile range as it increases. 1. 5. (b) female coyotes: uf = 89:24; s2. Male coyotes: um = 92:06; s2 f = 42:87887 m = 44:83586. The empirical c. d. f. is constructed by (cid:133)rst ordering the data (smallest to largest) to obtain the order statistic: 0. 01 0. 39 0. 43 0. 45 0. 52 0. 63 0. 72 0. 76. 85 0. 88. Then the empirical c. d. f. is in (cid:133)gure 12. 1 for q1. jpg. 2. 1. (a) l((cid:18)) = (cid:18)41e(cid:0)10(cid:18) and ^(cid:18) =4. 1 (b) e(cid:0)2^(cid:18) = 0:000275. In both cases if we maximize over (cid:18) we obtain (cid:18) = :10: (b) 140.
