Pretty sure just draw same line but a to r and b to s
Answer: 
Step-by-step explanation:
According to the empirical rule, the 95% confidence interval for the true population proportion is given by :-

Given : . The survey resulted in a sample proportion of p′=0.14, with a sampling standard deviation of σp′=0.02, who preferred reading an e-book.
Then, the 95% confidence interval for the true proportion of adults who prefer e-books will be :-

Hence, the 95% confidence interval for the true proportion of adults who prefer e-books= 
120-36 = 84 <==== what he has left
84/120×100% = percentage of what he has left
70% = percentage aka answer.
The answer to this problem is 5.
