Question 5
5 pts
A random sample of 200 shoppers at a local grocery store found that 135 of the 200 sampled would be willing to use self-checkout kiosks if the store installed them $ (\hat{p}=0.675) $.
Assuming you believe the initial results to be reasonable, how many samples would be required if you wanted to re-do the sample, construct a $ 95 \% $ confidence interval, and reduce the margin of error to 3\%?

Round your answer to the nearest whole number. Remember: with sample sizes we always round up!
