The restaurant owner randomly selects 200 customers and asks each customer if they would use an app to order food, if made available. He finds that 118 of them would use a restaurant app to order food. Calculate a 99% confidence interval and interpret this interval O a. 99% of the customers would use an app to order food. O b. We are 99% confident that the true proportion of customers who would use an app to order food is 60 Oc. We are 99% confident that the true proportion of customers who would use an app to order food is O d. We are 99% confident that between 50% and 68% of the sampled customers would use an app to and 68%
