Hello, Attached are some problems I need help with. Thanks.
18. Find the indicated binomial probability. Round to five decimal places when necessary. A company manufactures calculators in batches of 64 and there is a 4% rate of defects. Find the probability of getting exactly 3 defects in a batch. 3453.87152 2.6665 0.22105 2.88 19. Provide an appropriate response. Assume that the variable under consideration has a density curve. Given that 31.1% of all possible observations of the variable are less than 14, determine the area under the density curve that lies to the right of 14. 0.689 0.311 0.439 0.189 20. Fill in the blanks by standardizing the normally distributed variable. The amount of time that customers wait in line during peak hours at one bank is normally distributed with a mean of 13 minutes and a standard deviation of 2 minutes. The percentage of time that the waiting time lies between 15 and 17 minutes is equal to the area under the standard normal curve between ___ and ___. 1, 2 -2, -1 2, 4 1, 1.15 APPENDIX A Statistical Tables TABLE II Areas under the standard normal curve 0.09 0.0001 0.0001 0.0001 0.0002 0.0002 0.0003 0.0005 0.0007 0.0010 0.0014 0.0019 0.0026 0.0036 0.0048 0.08 0.0001 0.0001 0.0001 0.0002 0.0003 0.0004 0.0005 0.0007 0.0010 0.00 14 0.0020 0.0027 0.0037 0.0049 0.07 0.000 1 0.000 1 0.000 1 0.0002 0.0003 0.0004 0.0005 0.0008 0.001 1 0.001 5 0.002 1 0.0028 0.0038 0.005 1 Second decimal place in z 0.06 0.0001 0.0001 0.0001 0.0002 0.0003 0.0004 0.0006 0.0008 0.0011 0.0015 0.0021 0.0029 0.0039 0.0052 0.05 0.0001 0.0001 0.0001 0.0002 0.0003 0.0004 0.0006 0.0008 0.0011 0. 00 l 6 0.0022 0.0030 0.0040 0.0054 0.04 0.000 1 0.000 1 0.000 1 0.0002 0.0003 0.0004 0 0006 0.0008 0.0012 0.0016 0.0023 0.003 1 0.0041 0.0055 0.03 0.0001 0.0001 0.0001 0.0002 0.0003 0.0004 0.0006 0.0009 0.0012 0.0017 0.0023 0.0032 0.0043 0.0057 0.02 0.0001 0.0001 0.0001 0.0002 0.0003 0.0005 0.0006 0.0009 0.0013 0.0018 0.0024 0.0033 0.0044 0.0059 0.01 0.0001 0.0001 0.0002 0.0002 0.0003 0.0005 0.0007 0.0009 0.0013 0.0018 0.0025 0.0034 0.0045 0.0060 0.00 0.0000'r 0.0001 0.0001 0.0002 0.0002 0.0003 0.0005 0.0007 0.0010 0.0013 0.0019 0.0026 0.0035 0.0047 0.0062 3.9 3.8 3.7 3.6 3.5 3.4 3.3 3.2 3.1 3.0 2.9 2.8 2.7 2.6 2.5 \f\fTABLE II (cont) Areas under the standard normal curve 0.0 0.1 0.2 0.3 0.4 0.5 0.6 0. 7 0.8 0.9 1.0 1.1 1.2 1.3 1.4 0.00 0.5000 0.5398 0.5793 0.6179 0.6554 0.6915 0.7257 0.7580 0.7881 0.8159 0.8413 0.8643 0.8849 0.9032 0.9192 0.01 0.5040 0.5438 0.5832 0.6217 0.6591 0.6950 0.7291 0.7611 0.7910 0.8186 0.8438 0.8665 0.8869 0.9049 0.9207 0.02 0.5080 0.5478 0.5871 0.6255 0.6628 0.6985 0.7324 0.7642 0.7939 0. 8212 0. 8461 0. 8686 0. 8888 0.9066 0.9222 APPENDIX A Statistical Tables Second decimal place in z 0.03 0.5120 0.5517 0.5910 0.6293 0.6664 0.7019 0.7357 0.7673 0.7967 0. 8238 0.8485 0.8708 0.8907 0.9082 0.9236 0.04 0.5160 0.5557 0.5948 0.6331 0.6700 0.7054 0.73 89 0.7704 0.7995 0. 8264 0.8508 0.8729 0.8925 0.9099 0.925 1 0.05 0.5199 0.5596 0.5987 0.6368 0.6736 0.7088 0.7422 0.7734 0.8023 0.8289 0.853 1 0.8749 0.8944 0.9 1 1 5 0.9265 0.06 0.5239 0.5636 0.6026 0 6406 0.67 72 0.7123 0.7454 0.7764 0.805 1 0.83 l 5 0.8554 0.8770 0.8962 0.913 1 0.9279 0.07 0.5279 0.5675 0.6064 0.6443 0.6808 0.7157 0.7486 0.7794 0.8078 0.8340 0.8577 0.8790 0.8980 0.9147 0.9292 0.08 0.5319 0.5714 0.6103 0.6480 0.6844 0.7190 0.7517 0.7823 0.8106 0.8365 0.8599 0.8810 0.8997 0.9 162 0.9306 A-3 0.09 0.5359 0.5753 0.6141 0.6517 0.6879 0.7224 0.7549 0.7852 0.8133 0.8389 0.8621 0.8830 0.9015 0.9177 0.9319 \f\f
