please tell teachers what the subject is - needs probabilty and stats
I showed you how to do the last one, am leaving this more complicated version of the classic prisoner's dilemna problem for a stats teacher (I do physics)

Judy, Sam, Cindy -- or Whoever has posted the last 12 stats posts -- If you posted your ideas of the answers, a tutor might then help you.

Stats for the US and Canada show that in North America, the most births occur in September. Wonder if there is correlation based on the fact that Sept is 9 months after all those Christmas and New Year holidays??

probability and statistics
We haven't a clue about which stats book you're using. Plus -- most of us don't have multiple stats book here at home. With 41 numbers, 12.3 is the top of the 30th percentile.

<<the idealized uniform random number generator described.>> is not described We are not well staffed to answer stats questions; you would be better served elsewhere.

Design and create a class named Stats that has an array of 12 doubles as one of its member variables. The values in the array should be set by making 12 calls to a public member function named setValue that accepts two arguments, an integer indicating which value is being ...

Make a Venn diagram. 5% fail math only 25% fail both 10% fail stats only 60% pass both. Of the 30% (of all students) who failed math, 5/6 of that group (25% of all students)failed stats also. That is a conditional probability of 83.3%. Only 16.7% of the math-failing group pass...

To get P = .05, Ho needs to have μ ± 1.96 SD, Reject Ho, if value is outside that range. P is determined by Z score = (X-μ)/SD. Look up value in "area under normal distribution" in back of your stats text. Is "that" your SD? I hope this helps. If not, repost with ...

Expected number is .1*1000 = 100 SD is sqrt(n*p*q) = 1000*.1*.9 = 9.49 90 is 10 away from the mean and 10/9.48= 1.05 standard deviations away. Your stats book should have a cumulative normal distribution table. look up 1.05. I get .8531. Ergo, the probability of seeing more ...

The central tendency is the measure that best describes the data. The mean doesn't, because 5 is so much different than the other data. That leaves you median or mode. Check this site and decide which one fits this data. http://www.quickmba.com/stats/centralten/

.45 is .05 away from the mean or .05/.023 = 2.17 standard deviations away from the mean. Your stats book should have a cumulative normal distribution table. Look up 2.17. I get .9850, meaning that the probability of observing a sample where more than 45% is 1-.985 = .015=1.5...

http://science.widener.edu/svb/stats/error.html On the first, percent error is .02/10 x 100 absolute error is .02 On the last, you have to do some math. See the link error=sqrt (.02^2+ .02^2)=.028 then, use the formulas above.
