For Questions 1-3: In a survey of 220 randomly selected students at a certain college, 65.0% stated that there is not enough parking on campus. 1. (10 pts) How many of the 220 students sampled think that there is not enough parking on campus? 2. (10 pts) To the 95 per cent confidence level, find the confidence interval estimate of all students at that college who think that there is not enough parking on campus. Can we safely assume that less than 70% of all students at that college think that there is not enough parking on campus? 3. (10 pts) If we wanted to reduce the margin of error to 4.0 per cent, how big would our sample size have to be (again to the 95 per cent confidence level)? 4. (10 pts) In a certain city, a simple random sample of 36 new cars from several local dealerships reveals a mean price of $26,450 per car with a standard deviation of $1750. Construct a 90 per cent confidence interval estimate of the mean price of all new cars sold in that city. [Note: Table A-3 might be helpful since the population standard deviation is unknown.]
