and the critical value for this case would be:
The margin of error is given by:
And replacing we got:
And the margin of error for this case would be 
Step-by-step explanation:
For this case we have the following dataset given:
represent the sample size
represent the estimated proportion of interest
represent the confidence level
The significance level for this case would be and the critical value for this case would be:
The margin of error is given by:
And replacing we got:
And the margin of error for this case would be
Answer:
-9
Step-by-step explanation:
We are given the expression m–[(m–n)÷(−2)](−5). Substituting -4 for m and -6 for n, we get:
-4–[(-4 + 6)÷(−2)](−5)
We must do the work that appears inside parentheses first:
-4–[( 2 )÷(−2)](−5)
Next we must do the work that appears inside square brackets:
-4–[ -1 ](−5)
Multiplication comes next. The above expression becomes:
-4 - [ 5 ]
which in turn comes out to -9
