Find the margin of error for the given values of co, and n.
c=0.95,0 = 3.2, n=81
e=

The margin of error for the given values is  0.33725

Step-by-step explanation:

The margin of error expresses the maximum expected difference between the true population parameter and a sample estimate of that parameter. To be meaningful, the margin of error should be qualified by a probability statement (often expressed in the form of a confidence level).

Margin error =  

Now substituting the values we get

Margin error =  

Margin error =  

Margin error =  

Margin error =  

Margin error = 0.33725

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

the anwser is x< -17/2
