Question

A magazine provided results from a poll of 1000 adults who were asked to identify their favorite pie. Among the 1000 respondents, 11% chose chocolate pie, and the margin of error was given as plus or minus 4 percentage points. What values do modifying above p with caret, modifying above q with caret, n, e, and p represent? If the confidence level is 95%,what is the value of alpha?The value of modifying above p with caret is ?The value of modifyingabove q with caret is ?The value of n isthe margin of error.The sample proportion.The population proportion.Found from evaluating 1 minus modifyingabove p with caret .The sample size.The value of e isthe sample proportion.Found from evaluating 1 minus modifyingabove p with caret .The margin of error.The sample size.The population proportion.The value of p isfound from evaluating 1 minus modifyingabove p with caret .The sample proportion.The sample size.The population proportion.The margin of error.If the confidence level is 95%, what is the value of alpha?Alpha =? (type an integer or a decimal. Do not round.)

Answer 1

Answer:

α=significance level=0.05

P=sample proportion=0.11

q=1-p=1-0.11=0.89

n=sample size=1000

E=margin of error=0.04

95% of confidence interval=0.11±0.04

                                            =(0.07,0.15)

Then the confidence interval is 0.07<p<0.15
