Using it's concept, the standard deviation of the data-set is of 34.2.
<h3>What are the mean and the standard deviation of a data-set?</h3>
- The mean of a data-set is given by the <u>sum of all values in the data-set, divided by the number of values</u>.
- The standard deviation of a data-set is given by the <u>square root of the sum of the differences squared between each observation and the mean, divided by the number of values</u>.
Having this in mind, and inserting the data-set in the calculator, it is found that:
- The standard deviation is of 34.2.

Answer: 60 inches
Step-by-step explanation:
Let x be the height of son in the beginning of the year.
If the height is increased 110% at the end of the year , then his height in the end of the year = 110% of x
[since 110%=1.1]
Since, his height at the end of the year = 66 inches
Hence, the height of Mrs. Peters son in the beginning of the year is 60 inches.
Answer:
It is 20%.
Step-by-step explanation:
You minus 28 from 35 it will give 7 and then take 7 x 100 / 35 which will give you 20%
15% of 11.50 = 1.72 --> 11.50 - 1.725 = 9.77
9.77 - 1.50 = 8.27/2 = 4.14
