A study performed by Bridge Ratings found that in 2006, 58% of respondents said they use a cell phone while traveling in a vehicle (the survey participants were restricted to individuals who spent at least one hour per day commuting in their vehicle). For a sample of 250 adults who spend at least one hour per day commuting in a vehicle, approximate the probability that at least 150 use a cell phone while traveling in a vehicle. Use the normal approximation to the binomial distribution.
