Question

A magazine provided results from a poll of 1000 adults who were asked to identify their favorite pie. Among the 1000 ​respondents, 14​% chose chocolate​ pie, and the margin of error was given as +3 percentage points. What values do ​, ​, ​n, E, and p​ represent? If the confidence level is ​%, what is the value of ​?

Answer 1

The completion of the tabs are:

• The value of $\bar p$ is the sample proportion.
• The value of  $\bar q$ is found by evaluating $1-\=p$
• The value of n is the sample size.
• The value of E is the margin of error.
• The value of p is the population proportion.
• α = 0.05.

What is the margin of error.?

You may calculate how many percentage points your findings will deviate from the actual population figure by using something called a margin of error.

In conclusion

• The worth of p^ is the fraction of the sample.
• The worth of p^ is discovered by assessing
• The sample size is given by the number n.
• The margin of error is expressed as E's value.
• The population percentage is represented by the value of p.

• α = 0.05.

In conclusion,
