Surveyors recorded the number of
people at the Apple store who owned an Ipod Touch. They recorded the number of
people, x, that reported having one for each survey. The number of people
observed was normally distributed with a mean of 18 and a standard deviation of
5.8. Find the probability of observing at most 10 people with an Ipod Touch
during a survey. Round your answer to the nearest thousandth (using a z score
rounded to the nearest tenth).
