11. Assume the random variable X is normally distributed with mean u = 50 and standard deviation o = 7. Compute the probability. Be sure to draw a normal curve with the area corresponding to the probability shaded. P(X > 35) 25 Click the icon to view a table of areas under the normal curve. Which of the following normal curves corresponds to P(X > 35)? O A. B X C. 50 35 50 35 50 P(X > 35) = (Round to four decimal places as needed.) 25: Tables of Areas under the Normal Curve TABLE V Standard Normal Distribution 00 .01 02 .03 .04 .05 06 .07 .08 .09 -3.4 0.0003 0.0003 0.0003 0.0003 0.0003 0.0003 -3.3 0.0003 0.0003 0.0003 0.0002 0.0005 0.0005 0.0005 0.0004 0:0004 0.0004 0.0004 0.0004 0.0004 0.0003 -3.2 0.0407 0.0007 0.0006 0.0006 0.0006 0.0006 0.0006 -3.1 0.0005 0.0010 0.0009 0.0009 0.0009 0.0008 0.0008 0.0008 -3.0 0.0008 0.0007 0.0007 0.0013 0.0013 0.0012 0.0011 0.0010 0.0010 -2.9 0.0019 0.0018 0. 0.0017 0.0016 0.0016 0.0015 0.0015 0.0014 0.0014 0.0026 0.0025 0.0024 0.0125 0.0023 0.0020 0.0019 0.0033 0.0032 0.0031 0.0027 0.0047 0.0045 0.0044 0.0043 0.0041 0.0037 0.0062 0.0060 0.0059 0.0057 1.0055 0.0051 0.0049 0.0048 0.0082 0.0080 0.0078 0.0075 0.0073 0.0071 0.0068 0.0107 0.0066 0.0064 0.008 0.0087 0.0139 0.0113 0.0179 0.0174 0.0150 0.0146 0.0228 0.0222 0.0217 0.0212 0.0197 0.0192 0.0188 0.0183 -1.9 0.0287 0.0274 0.0268 0.0262 0.0256 0.0250 0.0244 0.0239 0.0233 -1.8 0.0359 0.0351 0.0344 0.033 0.0314 0.0294 0.0446 0.0436 0.0427 0.0375 0.0548 0.0537 0. 0.0516 0.0475 0.0465 0.0455 0.0668 0.0655 0.0643 0.0630 0.0582 0.0571 0.0559 00808 0.0793 0.0778 0.0764 0.0749 0.0721 0.0708 0.0694 0.0681 0.0968 0.0853 0.1151 0.1131 0.111 0.1020 0.1005 0.0985 0.1357 0.1335 0.1314 0.1292 0.1271 0.1210 0.1190 0.1170 -1.0 0.1587 0.1562 0.1539 0.1515 0.1492 0.1469 0.1446 0.1423 0.1401 0.1841 0.1814 0 0.1788 0.1762 0.1736 0.1711 0.1685 0.1660 0.1635 0.1611 0.2119 0.1922 0.1894 0.2420 3.2709 0.2177 0.2743 0.2514 0.2451 -0.5 0.3085 0.3050 0.3015 0.2912 0.2877 0.2843 0.2810 0.2776 0.3446 0.3409 0.3264 0.3192 0.3156 0.3821 0.3557 0.3520 0.3974 0.3936 0.3859 0.4602 0.436 0.4325 0.5000 0.4761 0.4721 0.4641 0.5000 0.5239 0.5279 0.1 05160 0.5319 0.5359 0.5398 0.5438 0.5478 0.5517 0.5557 0.5636 0.5675 05714 0.5753 0.5793 0.5832 0.5871 0.5910 0.5948 0.6026 0.6064 0.6103 0.6141 0.6179 LIZ90 0.6255 0.629 0.6331 0.6368 0.6406 0.6443 0.6517 0.6554 0.6591 0.6628 0.666 0.6700 0.6736 0.6772 0.6808 0.6844 0.6879 0.5 0.6915 0.6950 0.6985 0.7019 0.7054 0.7123 0.7157 0.7190 0.7224 0.6 0.7257 0.7291 0.7324 0.7357 0.7422 0.7454 0.7486 0.7517 0.7549 0.7 0.7580 0.7611 0.7642 0.767 0.7794 0.7823 0.7852 0.7881 0.7910 0.7939 0.8051 0.8078 0.8106 0.8133 0.8159 0.8186 0.8212 0.8238 0.8264 0.8315 0.8340 0.8365 0.8389 0.8413 0.8438 0.8485 0.8508 0.8531 0.8554 0.8577 0.8599 0.8621 0.8643 0.8665 1.2 0.870 0.8729 0.8770 0.8790 0.8810 0.8830 0.8849 0.8869 0.890 0.8962 0.8980 0.8997 0.9015 0.9032 0.9049 0.9066 0.9082 0.9099 0.9115 0.9131 0.9147 0.9162 0.9177 0.9192 0.9207 0.9222 0.9236 0.9251 0.9265 0.9279 0.9292 0.9306 0.9319 1.9332 0.9345 0.9357 0.9370 0.9382 0.9394 0.9406 0.9418 16 0.9452 0.9429 0.9441 0.9474 0.9525 0.9535 0.9545 17 0.9554 0.9641 0.9633 0.9649 0.9686 0.9693 0.9706 1.9 0.9713 0.9719 0.9726 0.9750 0.9756 0.9761 0.9772 0.9778 0.9783 0.9788 0.9793 0.9803 0.9808 0.9812 0,9817 2.1 0.9821 0.983 0.9854 0.9857 2.2 0.9861 0.9871 0.9881 0.9887 0.9890 23 0.9893 0.9896 0.9901 0.9909 0.9911 0.9913 0.9916 24 0.9918 0.9920 0.9922 0.9931 0.9932 0.9934 0.9936 2.5 0.9938 0.9940 0.9941 0.9943 0.9948 2.6 0.9952 0.9953 0.9955 0.9949 0.9951 0.9961 0.9962 0.9963 27 0.9965 0.9971 0.9972 0.9973 2.8 0.9974 0.9975 0.9976 0.9979 0.9979 29 0.9982 0.9982 0.9985 3.0 0.9987 0.9987 0.9987 0.9989 0.9989 3.1 0.9990 0.9990 0.9991 0.9991 3.2 0.9992 0.9993 0.9993 0.9993 0.9994 0.9995 0.9995 0.9995 0.9995 0.9996 0.9996 0.9996 0.9996 0.9996 7.2 0.9997 0 0.9997 0.9997 0.9997 0.9997 0.9997 0.9997 00 01 02 .03 .04 .05 -06 .07 YOU ANSWERED: C
