To discourage students from driving to campus, a university claims students spend an average of 20 minutes looking for a parking spot. One student does not believe it takes so long to find a spot. After taking a random sample of 45 students, a sample mean of 17.4 minutes to find a parking spot was calculated.
To assess the evidence provided by the sample data, what is the appropriate question to ask?
1. The true mean amount of time needed to find a parking spot 17.4 minutes?
2. How likely is it that the true mean amount of time needed to find a parking spot is 20 minutes?
3. How likely is it that, in a sample of 45, the true mean amount of time needed to find a parking spot is 17.4 minutes or less if the true mean is 20?
4. How likely is it that, in a sample of 45, the true mean amount of time needed to find a parking spot is less than 20 minutes?
