Determine the point estimate of the population proportion, the margin of error for the following confidence interval, and the
number of individuals in the sample with the specified characteristic, x, for the sample size provided.
1 answer:
Answer:
point of estimate p = x/n
Step-by-step explanation:
p is the point estimate for the population , x is the number of success, n is the sample size.
p = Upper bound + Lower bond/ 2 for population proportion
x = Upper bond + Lower bond /2 for population mean
E = Upper bond - Lower bond /2 E is margin of error

The equation in slope intercept for is y = 5/2x + 4
The y intercept is 4
1. x
2. x + 2
3. x + 4
x + 4 + 2x = 25. Second option is the answer.
Combine like terms
3x + 4 = 25
Subtract 4 from both sides
3x = 21
Divide both sides by 3
x = 7
