Answer 1

In the provided question, there are 4 types of parking lots. They are lot 38, lot 18, Top Garage, and Premium. The average time to park in each parking lot is compared using ANOVA.

According to the provided ANOVA table, the p-value corresponding to the f test is 0.017 which larger then 0.01 but smaller than 0.05. So, it can be concluded that the null hypothesis will be rejected at 5% significance level. That is, it can be said that the average time to park in at least one parking place is different than the other.

In the question, the grouping information using Tukey test is also provided. The maximum time is required to park in the Top garage whereas the minimum time is required to park the car in premium.

Since, people want to save the parking time, the people should park in the premium parking lot. Therefore, it can be concluded that the premium parking lot is recommended.
