Can I please get help with question b?
![Suppose a poll utilizing a random sample of 1,503 adults ages 18 or older was conducted in April 2018. The survey indicated a majority of Americans (55%) say driverless cars will be common in the
next 10 years. The following question was asked with possible responses 'Within 5 years', '6-10 years', '11-15 years', '16-20 years', 'Longer than that', 'Don't know':
"Thinking about fully automated, 'driverless cars,' cars that use technology to drive and do not need a human driver, based on what you have heard or read, how soon do you think
driverless cars will be commonly used in the [United States]?"
The figure shows a summary of results of the survey in a histogram indicating the percentage of the total responses in different time intervals.
