_________________________
The mean of 0.592 seems
a little large compared to the expected value of 0.5. To
see if the difference is statistically significant, we will use
the statistics computed here to construct a confidence
interval for the true mean of the population of random
numbers and see whether or not this interval contains 0,5.
5. Press S3 to close the computed statistics window.
