Question: Calculate the probability for the following values assuming a normal distribution. Round the calculated z-statistic to 2 decimal places before using the standard normal


Calculate the probability for the following values assuming a normal distribution. Round the calculated z-statistic to 2 decimal places before using the standard normal table (do not interpolate). Answer must be 4 decimal places. a. = 5.0, o = 4.0, Prob(X2 12.0) b. = 8.0, o = 3.0, Prob(X 12.5) [4] 4 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 1.1 1.2 APPENDIX D Standard Normal Distribution Table 0 0.0000 0,0398 0.0793 0.1179 0.8 0.2881 0,9 0.3159 1.0 0.3413 0.1554 0.1915 2.2 2.3 0.2257 0,2580 1.3 0,4032 1.4 0.4192 1.5 0,4332 2.6 2.7 2.8 2.9 3.0 0.3643 0.3849 1.6 0.4452 1.7 0.4554 0.4641 1.8 1.9 0.4713 2.0 0.4772 2.1 0,4821 0,4861 0.4893 2.4 0.4918 2.5 0,4938 0,4953 0,4965 0,4974 0.4981 0,4987 0.01 0.0040 0.0438 0.0832 0.1217 0.1591 0.1950 0.2291 0.2611 0,2910 0.3186 0.3438 0.3665 0.3869 0.4049 0.4207 0.4345 0.4463 0.4564 04649 0.4719 0.4778 0.4826 0.4864 0.4896 0,4920 0,4940 0,4955 0.4966 0.4975 0.4982 0,4987 0.02 0.0080 0.0478 0.0871 0.1255 0.1628 0.1985 0.2324 0.2642 0.2939 0.3212 0.3461 0.3686 0.3888 0.4066 0.4222 0.4357 0.4474 0,4573 0.4656 0.4726 0.4783 0,4830 0.4868 0.4898 0,4922 0.4941 0.4956 0.4967 0.4976 0,4982 0,4987 0.03 0.0120 0.0517 0.0910 0.1293 0.1664 0.2019 0.2357 0.2673 0.2967 0.3238 0.3485 0.3708 0.3907 0.4082 0.4236 0.4370 0.4484 0,4582 04664 0.4732 0.4788 0.4834 0.4871 0,4901 0.4925 0.4943 0.4957 0.4968 0.4977 0.4983 0.4988 0.04 0.0160 0.0557 0.0948 0.1331 0.1700 0.2054 0,2389 0.2704 0.2995 0.3264 0.3508 0.3729 0.3925 0.4099 0.4251 0.4382 0.4495 0.4591 0.4671 0.4738 0.4793 0.4838 0.4875 0,4904 0.4927 0.4945 0.4959 0.4969 0.4977 0,4984 0.4988 0.05 0.0199 0.0596 0.0987 0.1368 0.1736 0.2088 0.2422 0.2734 0.3023 0.3289 03531 03749 0.3944 0.4115 0.4265 0.4394 0.4505 0,4599 0.4678 0.4744 0.4798 0.4842 0.4878 0.4906 0.4929 0.4946 0.4960 0.4970 0.4978 0.4984 0.4989 0.3944 z = 1.25 0.06 0.0239 0.0636 0.1026 0.1406 0.1772 0.2123 0.2454 0.2764 0.3051 0.3315 0:3554 0.3770 0.3962 0.4131 0.4279 0.4406 0.4515 0.4608 0.4686 0.4750 0.4803 0.4846 0.4881 0.4909 0.4931 0.4948 0,4961 0.4971 0.4979 0.4985 0.4989 0.07 0.0279 0.0675 0.1064 0.1443 0.1808 0.2157 0.2486 0.2794 0.3078 0.3340 0.3577 0.3790 0.3980 0.4147 0.4292 0.4418 0.4525 0.4616 0.4693 0.4756 0.4808 0.4850 0.4884 0.4911 0.4932 0.4949 0.4962 0.4972 0.4979 0.4985 0.4989 0.08 0.0319 0.0714 0.1103 0.1480 0.1844 0.2190 0.2517 0.2823 0.3106 0.3365 0.3599 0.3810 0.3997 0.4162 0.4306 0.4429 0.4535 0.4625 0.4699 0.4761 0.4812 0.4854 0.4887 0.4913 0.4934 0.4951 0.4963 0.4973 0.4980 0.4986 0.4990 0.09 0.0359 0.0753 0.1141 0.1517 0.1879 0.2224 0.2549 0.2852 0.3133 0.3389 0.3621 0.3830 0.4015 0.4177 0.4319 0.4441 0.4545 0.4633 0.4706 0.4767 0.4817 0.4857 0.4890 0.4916 0.4936 0.4952 0.4964 0.4974 0.4981 0.4986 0,4990 APPENDIX F Values of t for Selected Probabilities Conf.
