Answer:
116 students
Step-by-step explanation:
The standard deviation for a proportion is:
For any measured sample proportion x, the z score is given by:
The population proportion is 0.53
At the 14th percentile, the corresponding z-score is z =-1.08.
Since 0.48 is at the 14th percentile, the standard deviation is:
Therefore, the sample size 'n' is given by:
The sample size must have been of 116 students.
Answer:v = 9
Step-by-step explanation:
Simplifying
2(3v + 8) = 70
Reorder the terms:
2(8 + 3v) = 70
(8 * 2 + 3v * 2) = 70
(16 + 6v) = 70
Solving
16 + 6v = 70
Solving for variable 'v'.
Move all terms containing v to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 6v = 70 + -16
Combine like terms: 16 + -16 = 0
0 + 6v = 70 + -16
6v = 70 + -16
Combine like terms: 70 + -16 = 54
6v = 54
Divide each side by '6'.
v = 9
