Stats and Prob1 What is the probability that an outcome z is less than 0.5? I have discovered a truly marvellous signature, which this margin is too narrow to contain. Fermat Give me a lever long enough and a fulcrum on which to place it, and I shall move the world. Archimedes Young man, in mathematics you don't understand things. You just get used to them.

Re: Stats and ProbHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20130605 22:54:44
Re: Stats and ProbOkay, thanks. I realize they are a lot though. I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: Stats and Prob5 is correct and 6 is incorrect. I will check the others.

Re: Stats and Prob10) Is a good rounding of the answer. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #6 20130605 23:03:12

Re: Stats and ProbI did it again and got 0.0062. 7 that is. Now I will do 8. Getting 0.0062 for 8 too!

Re: Stats and ProbAnd I am getting 0.0062 for 8 as well. I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: Stats and ProbThanks everyone, is 8 correct now? And just saw Stefy say that 6 is wrong. Now I am getting for it (as there are two answers and I took the average). So many mistakes due to carelessness... I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: Stats and ProbHm? There is only one onswer for 6.

Re: Stats and Prob0.028 + 0.132 + 0.309 = 0.469 and = 0.472 – 0.002 = 0.470 I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: Stats and Prob12) Looks to be a good rounding. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #19 20130605 23:22:50
Re: Stats and ProbThankyou both very much. I have discovered a truly marvellous signature, which this margin is too narrow to contain.

Re: Stats and Prob3 is correct.

Re: Stats and ProbAgain, what was your answer for 6? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #22 20130605 23:28:24
Re: Stats and ProbThe exact answer for 6 is 0.46935 .

Re: Stats and ProbI am not getting that for 6?! In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #25 20130605 23:31:58
