How does a computer process data? * A. Computer processes combinations of 1s (on) and Os (off) as a form a code and
translates it into data.
B. Computer processes combinations of base 10 numbers using different amounts of
voltage and translates it into data
C. Computer processes number of lights on to tally and translates it into data
D. All of the above

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
