The mean, median, standard deviation, and interquartile range for each data set is given below.
<h3>What is the definition of Interquartile Range (IQR)?</h3>
When arranged from lowest to highest, the IQR represents the central 50% of values.
Find the median (middle value) of the lower and higher half of the data to get the interquartile range (IQR).
These are the quartile 1 (Q1) and quartile 3 (Q3) values (Q3). The difference between Q3 and Q1 is the IQR.
<h3>What are the measures of central tendency for Manuels Data?</h3>
Using the statistical tool, the following were arrived at:
- Standard Deviation = 3.13961
- Mean = 8
- Median = 8
- IQR = Q3-Q1 = 10 - 6 = 4
<h3>What are the measures of central tendency for Grethcen's Data?</h3>
Using the statistical tool, the following were arrived at:
- Standard Deviation = 4.68737.
- Mean = 9.6
- Median = 9
- IQR = IQR = Q3-Q1 = 12 - 7 = 5.

The value of f(-1) is -11 if the function f(n) = 8n - 3 after plugging the value of n is -1
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
f(n) = 8n - 3
g(n) = 3n - 10
To find the value of f(-1) first plug n = -1 in the function f(n)
f(-1) = 8(-1) - 3
f(-1) = -8 - 3
f(-1) = -11
Thus, the value of f(-1) is -11 if the function f(n) = 8n - 3 after plugging the value of n is -1

B = 7, a = 5. So a + b is 13.
The answer is e=289. You just minus 1201 by 912 to get 289.
