What percentage of subjects obtained scores less than 65?
828638
Assuming the population is normal, to calculate the percentage of subjects obtaining 65 or below, we find the Z score that corresponds to 65:\n\nZ score \n= ( score - mean ) / standard deviation\n= (65 - 80) / 6\n= -2.5\n\nLooking up a Z-score of -2.5 in a 'table of standard normal probabilities' (or using statistical software), gives 0.0062 which is 0.62%. \n\nAs for the confidence interval.. it is 'estimate' +/- 'margin of error'\n80 +/- 1.95 * 6 / sqrt(100)\n80 +/- 1.176\nThe 95% confidence interval (78.824,81.176)\n\n(I.e we can be 95% confident that the true population mean lies between 78.824 and 81.176, and this is based our the sample of 100 subjects which had a mean of 80)

If a 68-year-old person has an IQ of 122, it means that his intelligence is above average. This is because the average score for a 68-year-old person is 100.

I believe it's 140.   I know that you have to have over 130 to be able to belong to Mensa.  This is an orginaization with the smartest people. only about the top 1 to 2% of population are above 130 IQ\n\n\nA top 2% mark in any of these frequently used tests below qualifies you for entry to Mensa. The minimum test mark to get into Mensa is:  \nCattell III B - 148  \nCulture Fair - 132  \nRavens Advanced Matrices - 135  \nRavens Standard Matrices - 131 \nWechsler Scales - 132

166 really?? I would think you could figure it out. LOL\n\ntop score 300. average 110-115, genius (top 2 %) 130+\n\nIt was estimated that Marilyn Vos Savants IQ was 230. but when IQ gets very high it is impossible to tell. There actually is not top score but it is estimated that it is almost beyond improbability for a homo sapiens to score higher than 300 and not be another species.\n\nPart of the measuring problem is ceiling bump. i.e. how does a person with an IQ of 135 design a test to quantify the IQ of someone with and IQ of 200 or 250.\n\nWith an IQ of 166 one thing that you Will notice. People that have IQ of less than say 120 will notice that you are smart but not be able to discern how smart. People that are over 135 can discern the difference between two people one with say an IQ of 145 an another with an IQ of 165.

lol...if you have to ask, you must not be too concerned with the results of the test. BTW, 2400 is a perfect score.

650+. I think the average is about 680.

.276%, 75%, 51%, 22.5% and 65% I think

I would say the average is probably around 20-30. If you look closely at the questions, there are a lot of eclectic topics which you know aren’t being asked by 12 year olds, like “What form of exempts can I get on my W-2?” But there are plenty of older audiences out there too. So really every age seems to be here - just the 20-30 are the most prominent.

64) b\n\n65)b\n\n66)c\n\n90 percent sure

target level is below 180 but ideally below 140 (but this will carry a higher risk of hyoglycemia).\nnever make it below 80 or even 100 as hypoglycemia will be a real danger.

According to this study, 17.2%.  See link.

I am 9 but mine scored in at 146, so I would say yours is quite low.

63 and 65 would both work....my guess, having to choose between the two, would be 65.

the average age should be around 22

I like history and math.  Study ancient physics and know that 161% means more than one person would be sharing the mark!!  I think you mean that you ned 161% to pass, but it would take two of you to do it.  If you have 19.5% in both subjects you need to ask for help.

Well 70 is passing.The battery 473 is a newer test and rumor has it  that 100 is  not possible on this test.\nI have the most recent study guide by TParnell an expert  postal test taker and author of postal exam guides he states in his book that his postal contacts and feed back from customers  have confirmed that "the highest scores recorded for the 473 exam so far are in the mid 80's" ( this is from tparnell book)\nHe also states  in the book  "Don't be discouraged by your exam score! Think of 85 as the highest possible score , not 100. If your score is 83 , its time to celebrate.You are only 2 points from a perfect score of 85.And if your score is in the 70's ,that's not nearly as bad as it sounds.you are only a hand full of points away from a perfect score of 85" ( this is from tparnell book)\nHe also states that "whenever he took the test and scored anywhere in the 80's in every case I was almost immediately received an invitation to an employment interview" he also states that many of his customers with scores in the 80's were contacted quickly" ( this is from tparnell book) \nSo I think 80 is pretty good. I took the 480 yearss ago when I got hired and scored in the 90's.My ex was hired with a score of 70! Good luck  <-------this is from me !
