Step-by-step explanation:
Using the rules of radicals/ exponents
×
=
⇔
Simplifying each term
7 = 7
x
= x × ×
= x × 3 ×
= 3 ×
= 3
Subtracting the 2 simplified like terms, that is
7 - 3
= 4 ← return to radical form
= 4
Answer:
0.069
Step-by-step explanation:
The given data set is
0.92, 0.87, 0.88, 0.82, 0.82, 0.87, 0.97, 0.86, 0.89, 0.84, 0.81, 0.88, 0.77, 0.86, 0.93, 0.84, 0.72, 0.82, 0.74, 0.83, 0.93, 0.75, 0.79, 0.91, 0.84, 0.91, 0.88, 0.88, 0.83, 0.78, 0.99, 0.81, 0.78, 0.75, 0.82, 0.76, 0.82, 0.87, 0.91, 0.77, 0.72, 0.94, 0.71, 0.73, 0.81, 0.81, 0.86, 0.93, 0.93, 0.82.
Formula for mean:
Sum of all terms = 41.98
Mean of the data set is
Formula for standard deviation for population:
Formula for standard deviation for sample:
Therefore, the standard deviation of the data set is 0.069.
