Answer #1

To find the margin of error for given, confidence (c) = 0.80 , sample size (n) = 26 and standard deviation (s) = 6

We know that, margin of error is calculated as,

where t* is the value from t distribution with (n-1) degrees of freedom and level of significance,

Thus,

Therefore, margin of error is 1.5489
