Question:

Recall the Empirical Rule from Chapter 3. It states that if the data is bell shaped, then the interval μ ± σ contains approximately 68% of the values, μ ± 2 s contains approximately 95%, and μ ± 3 s contains virtually all of the data values.
The bell-shaped referenced is the normal Verify that a standard normal contains approximately 68% of the values in the interval μ ± σ.
b. Verify that a standard normal contains approximately 95% of the values in the interval μ ± 2σ.
c. Verify that a standard normal contains virtually all of the data in the interval μ ± 3σ. Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
