Question

g A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 ​respondents, 14​% chose chocolate​ pie, and the margin of error was given as plus or minus3 percentage points. What values do ModifyingAbove p with caret​, ModifyingAbove q with caret​, ​n, E, and p​ represent? If the confidence level is 90​%, what is the value of alpha​? The value of ModifyingAbove p with caret is ▼ The value of ModifyingAbove q with caret is ▼ found from evaluating 1 minus ModifyingAbove p with caret . the sample proportion. the sample size. the margin of error. the population proportion. The value of n is ▼ the population proportion. found from evaluating 1 minus ModifyingAbove p with caret . the sample size. the sample proportion. the margin of error. The value of E is ▼ the population proportion. the sample size. the margin of error. found from evaluating 1 minus ModifyingAbove p with caret . the sample proportion. The value of p is ▼ the sample size. the population proportion. found from evaluating 1 minus ModifyingAbove p with caret . the sample proportion. the margin of error. If the confidence level is 90​%, what is the value of alpha​? alphaequals nothing ​(Type an integer or a decimal. Do not​ round.)

Answer 1

\alpha = 0.10

Explanation:

We can use the following method to solve the given problem

\hat{p} = sample proportion = 0.14

\hat{q} = found from evaluating 1 - \hat{p} = 0.86

n = sample size = 500

E = margin of error = 0.05

p = population proportion

Given,

Confidence level = 90%

Significance level \alpha = 1 - 0.90

= 0.10

\alpha = 0.10
