Note: a number of the routines within the newer ninth version also are present in the eighth variation of the textbook, simply numbered another way. This answer handbook can frequently nonetheless be used with the ninth version by means of matching the workouts among the eighth and ninth versions.

ninety% self belief period for the inhabitants suggest is √ √ 48.50 − (1.796)(1.5/ 12) < µ < 48.50 + (1.796)(1.5/ 12), or 47.722 < µ < 49.278. 9.16 n = 12, x¯ = 79.3, s = 7.8, and t0.025 = 2.201 with eleven levels of freedom. A ninety five% self belief period for the inhabitants suggest is √ √ 79.3 − (2.201)(7.8/ 12) < µ < 79.3 + (2.201)(7.8/ 12), or 74.34 < µ < 84.26. 105 suggestions for routines in bankruptcy nine 9.17 n = 25, x ¯ = 325.05, s = 1/2, γ = 5%, and 1 − α = 90%, with ok = 2.208. So, 325.05 ± (2.208)(0.5).
