Answer:
- 6.547
Step-by-step explanation:
Given that:
Sample size (n) = 1207
p = 0.85
p0 = 0.92
The test statistic :
Z = (p - p0) / √(p0(1 - p0) / n)
Z = (0.85 - 0.92) / √(0.92(1 - 0.85) / 1207)
Z = - 0.07 / √(0.92(0.15) / 1207)
Z = - 0.07 / √0.0001143
Z = - 0.07 / 0.0106926
Z = - 6.5465446
Z = - 6.547
Answer:
x not given
therefore no answer for x
Answer: x = 14
Step-by-step explanation:
-x+14 = 0
Subtract 14 from both sides of the equation :
-x = -14
Multiply both sides of the equation by (-1) : x = 14
