99.7 percentage of the data lies between 140 and 212 pounds when the distribution of the standard deviation is normal.

<h3>What is standard deviation?</h3>

Any given quantity, which is used to express that how many observations  differ from others in the total observations of a data, is referred to as standard deviation. It is represented by σ.

To calculate the percentage of data lying between the given values, we will use the formula of empirical method and the given information to compute as under,

\rm P(mu-3\ x\ \sigma < X < \mu + 3\ x\ \sigma)

Solving further,

\rm P(176-3\ x\ \12 < X < \176+ 3\ x\  12) = 0.997

Hence, the significance upon the standard deviation of data weighted by Naomi is as aforementioned.

Amanda [17]

Answer:

Explanation:

Current interest rate on one year bond = 5%
