How to compute mean please give samples - Casio FX991ES Scientific Calculator

I'm assuming here that 1,040 means one thousand and forty, not a metric decimal comma.

First we need the Std Dev of the mean value itself. This is

s / sqrt (n) = 21000 / sqrt (1040) = 651.2

Then the confidence interval for the mean value is

mean value ± Z * ( s / sqrt (n) )

where Z is an estimator related to the required confide

CL Z
99% 2.576
98% 2.326
95% 1.96
90% 1.645

So for a confidence of 95% the margin of error for the true value of the mean is

46239 ± 1.96 * 651.2 or
46239 ± 1276.3

that is, the mean of a sample from this process will be in this range to 95% confidence.

The margin of error for a future sample value would be

46239 ± 1.96 * 21000 or

46239 ± 41160

that is, a single sample value from this process will be in this range to 95% confidence.
.

First you need the Std Error of the mean value, a measure of the dispersion of that mean value.

SE = sample std deviation / sqrt (sample size)
= 100 / sqrt (64)
= 100 / 8
= 12.5

Then we use a figure for the number of std errors either side of the mean value, which make up a 95 % confidence interval. This is ± 1.96 std errors, from tables of the Normal Distribution.

So the confidence interval is

350 ± 1.96 * 12.5 or

374.5 to 325.5

Go online and download a program called recuvva. It may be able to get your pictures back

I'm not familliar with this device but from the ERROR it spits out you seam to have a configuration problem, since it is a TAPE wich is 44 Khz SAMPLE RATE, check the sampling rate settings it might be to high or to low

Hope this helps!

Hey!

Try checking the Time and Date settings of the computer. Time and Date settings can greatly affect programs that access the internet. Try correcting the Time and Date settings. After correcting it, try browsing some websites where you get certificate errors.

After doing that, restart your computer. If the Time and Date is wrong again, it means that there is a problem with the CMOS battery(complimentary metal oxide semiconductor). This battery saves the basic settings of your computer which includes Time and Date settings, boot up device settings, etc. If that's out of charge, best option is to replace it. Here's an sample image of it. It's just like a watch battery but a bit bigger.

Hope this helps! :D

This usually means your digital buffer overloads. When you have added several layers on to a sound it can be to much. Try to sample the sound again. If it comes back try to take the sample in a lower bitrate. Maybe your maybe can not keep up with the bitrate.

UNINSTALL your old version of Java, then Install the updated version, - this works, in that order....

Random number generators on computers are not really random. They need to be "seeded". If you seed the random number generator with the same seed each time you will generate the same list of numbers. A common technique in computer programming is to seed the random number generator with a value like the number of seconds that has occurred since midnight. This gives you the illusion of real random numbers.

Look up the word "Seed" in your calculator documentation and it will most likely tell you how this is accomplished on the TI calculators.
