Amagazine provided results from a poll of 1500 adults who were asked to identify their favorite pie. among the 1500 respondents, 12% chose chocolate pie, and the margin of error was given as plus or minus5 percentage points. what values do modifyingabove p with caret, modifyingabove q with caret, n, e, and p represent? if the confidence level is 99%, what is the value of alpha?

Where : is the margin of error , n is the sample size , p is the sample proportion of success and is the significance level.

Given : Confidence level :

Then , Significance level :

Sample size :

Sample proportion of respondents chose chocolate pie:

Margin of error :

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
