How To Find Margin Of Error With Confidence Interval
MEMORY_MANAGEMENT BSOD, I don't remember the specific code. Shortly after, the PSU broke and I was only able to get a new one now. I only ran Windows for a few minutes, and I didn't have any BSODs, however I decided that it would probably be a good idea to run memtest to make sure the error doesn't happen again without knowing if it's coming or not. I've been running this program for 3 hours now, and I'm planning to let it run overnight. Errors have been found already, but I'm not sure how to proceed should the error count halt or continue to increase. Here are the parameters: CPU: AMD FX-6350 @ 3.9 GHz L1 Cache: 80K 33518 MB/s L2 Cache: 2048K 24951 MB/s L3 Cache: 8192K 10212 MB/s Memory: 4078M 5061 MB/s Iterations: 3 AdrsMode: 64bit Pass: 2 Errors: 27 Error Confidence Value: 222 Lowest Error Address: 00083bb6cf0 - 2107.7 MB Highest Error Address: 00083bb6cf0 - 2107.7 MB Bits in Error Mask: 00000040 Bits in Error - Total: 1 Min: 1 Max: 1 Avg: 1 Max Contiguous Errors: 1 Test 4: 11 errors Test 7: 16 errors The other tests report no errors. -- Should I be concerned? This report doesn't seem very threatening like reports from different computers with really bad RAM, but I am not experienced enough in this subject to make a judgment. EDIT: Aft

I have 16 Gb RAM (2x8GB) (Corsair Vengance LP 1600Mhz DDR3). I am going to remove each module in turn and test the remainig one on its own.......currently running at the moment.... The reason for using Memtest is that my computer started freezing up yesterday. I had to reboot using the restart button on the front. However only the fan starts and won't boot - the screen stays blank...... after a few attempts (having to power off with the button on the front) I get this message: ('American Mega Trends' logo).....Overclocking Failed please enter setup to re-configure sytstem. Press F1 to run setup. So I pressed F1 and set 'Default' settings option in Bios and it boots. However the next time I try to boot the same thing happens. I have uninstalled some recent programs and updated the BIOS. Any ideas what all this might mean or what I should do next? Thanks J Windows 8.1 64bit

Estimation Requirements The approach described in this lesson is valid whenever the following conditions are met: The sampling method is simple random sampling. The sampling distribution is approximately normally distributed. Generally, the sampling distribution will be approximately normally distributed when the sample margin of size is greater than or equal to 30. The Variability of the Sample Mean To construct a confidence interval for a sample mean, we need to know the variability of the sample mean. This means we need to know how to compute the standard deviation or the standard error of the sampling distribution. Suppose k possible samples of size n can be selected from a population of size N. The standard deviation of the sampling distribution is the "average" margin of error deviation between the k sample means and the true population mean, μ. The standard deviation of the sample mean σx is: σx = σ * sqrt{ ( 1/n ) * ( 1 - n/N ) * [ N / ( N - 1 ) ] } where σ is the standard deviation of the population, N is the population size, and n is the sample size. When the population size is much larger (at least 20 times larger) than the sample size, the standard deviation can be approximated by: σx = σ / sqrt( n ) When the standard deviation of the population σ is unknown, the standard deviation of the sampling distribution cannot be calculated. Under these circumstances, use the standard error. The standard error (SE) can be calculated from the equation below. SEx = s * sqrt{ ( 1/n ) * ( 1 - n/N ) * [ N / ( N - 1 ) ] } where s is the standard deviation of the sample, N is the population size, and n is the sample size. When the population size is much larger (at least 20 times larger) than the sample size, the standard error can be approximated by: SEx = s / sqrt( n ) Note: In real-world analyses, the standard deviation of the population is seldom known. Therefore, the standard error is used more often than the standard deviation. Ale
