Alright so .25 oz is 1/4 of 1oz. Therefore you take 28 and divide it by 4 and get 7.
Then take 3500 and divide it by 7 which makes 500 thumb tacks.
I think idk though.
Using the z-distribution, as we are working with a proportion, it is found that samples of 937 should be taken.
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:

In which:
is the sample proportion.
The margin of error is given by:

In this problem, we have that:
- The estimate is of
.
- The margin of error is of M = 0.03.
- 95% confidence level, hence
, z is the value of Z that has a p-value of
, so
.
Then, we solve for n to find the minimum sample size.






Rounding up, it is found that samples of 937 should be taken.
