3 AntwortenMathematicsvor 4 JahrenSTATISTICS: An earlier study claim that U.S. adults spend an average of 114 minutes with their families per day and...?
An earlier study claim that U.S. adults spend an average of 114 minutes with their families per day and its standard deviation is 11 minutes. A recently taken sample of 25 adults showed that they spent an average of 109 minutes per day with their families. Assume that the time spent by adults with their families has an approximate normal distribution.
a) What is the probability that U.S. adults spend a sample average less than 109 minutes per day with their families provided that the current mean and standard deviation are correct?
b) Does the sample information support that the mean time spent currently by all adults with their families is less than 114 minutes a day? Explain your conclusion in words.

1 AntwortMathematicsvor 8 JahrenATI Radeon 4850 vs 4870?
Should I get a Radeon 4850 or 4870?
4850 is 512mb GDDR3 for $95 after rebate
4870 is 1gb GDDR5 for $190
I am not a gamer but I want a decent card to play GTA 4.
Is 1024mb and GDDR5 worth paying twice as much for or is it not going to be noticable?
See links below. Thanks for your help.
2 AntwortenDesktopsvor 1 JahrzehntWhere is Ron Paul in the news?
Why is it that presidential candidate Ron Paul is almost never mentioned in any of the news channels or websites including Yahoo. When Fox News had the republicans debate Ron Paul received more support from viewers than any other republican yet it seems like the media treats him as an outsider and tries to ignore him completely. Is this some sort of a mafia where only the rich candidates get to be featured in the news?
