Answer:
1568
Step-by-step explanation:
The computation of the minimum sample size is shown below:
Given that
Error E = 11
The population standard deviation =217
Confidence level 1-α = 95%
Now following formula should be used
n > (Zalpha ÷ 2 × sigma ÷ E)^2
As we know that
Zalpha ÷ 2= 1.96
Now the sample size is
n> (1.96 × 202 ÷ 10)^2
= 1568
Rule: whatever you do to the left side, you must do on the right side. This means when you minus 80 on the left, you must minus 80 on the right as this continues to equate the two sides.
You see you can break it up by 30's, 30 is its greatest common factor, so 30 can go into 90 3 times and 120 4 times so it turns to= 3/4
