Answer:

And the value for n rounded up would be n = 174
Step-by-step explanation:
We have the following info given:
previous estimation for the deviation
the margin of error desired
represent the confidence
The Margin of error is given by:

If we solve for the value of n we got:

For this problem we know that the confidence is 98% so then the significance level would be
and the critical value would be:

And replacing we got:

And the value for n rounded up would be n = 174
Answer:
110
Step-by-step explanation:
40% is the same as 40/100, which is equal to 0.4. Therefore, you can write the following equation:
0.4x=44
Divide both sides by 0.4 to isolate x:
x=44/0.4=110
