They collected a sample of {a} and 7 of them were defective. Give the upper bound.  Round your answer to four decimal places. Provide support for your answer. 

Suppose we wanted to use this data to test whether the true average hours of screen time is different from 4 hours.  Let’s also suppose that the true average really is 4 hours. Would we have made an error based on the result of our confidence interval. If so, what type of error would we have made? Explain.
