The Pizza Place introduced a new thin crust pizza. On a Friday afternoon, their busiest day, they sampled 200 customers who ordered pizza with the new thin crust and 120 said they would order pizza with this new crust again. Calculate a 98% confidence interval for the proportion of customers who would order the new thin crust pizza again.

p' = (round to 1 decimal place)

q' = (round to 1 decimal place)

E = (round to 2 decimal places)

The 98% confidence interval is from to (round to 2 decimal places)
