To find the margin of error for the mean of a normally distributed
population from a sample, the critical probability, [tex]\alpha[/tex], is obtained by
[tex]p=1-\alpha[/tex]
where p is the confidence level.
Assuming a confidence level of 86%, the critical probability is given by
[tex] \alpha =1-0.86=0.14[/tex]
[tex]p=1-\alpha[/tex]
where p is the confidence level.
Assuming a confidence level of 86%, the critical probability is given by
[tex] \alpha =1-0.86=0.14[/tex]
