Use the site https://www.random.org/gaussian-distributions/ to generate a set of 100 random numbers from a Normal distribution with a mean of 1.0 and a standard deviation of 2.0.
1) Record these numbers in Excel and use them to generate a 2-sided 95% confidence interval
for the generated data, assuming an unknown mean but a known standard deviation of 2.0.
2) For a Normal(1.0, 2.0) distribution, calculate the range that we would expect 95% of our observations to fall into; explain why this range differs from the 95% CI calculated in step 2.
