Elon Musk wanted to increase the amount of time people spend in Tesla dealerships by adding a racing simulator. If customers spent 1 hour or more , then the company would decide to add them to every dealership. In order to test how much time on average the customers spent, Elon randomly sampled 5 customers and kept track of how long they spent in the dealership on a stopwatch. One person spent the entire day at the race simulator, but others only spent a few minutes. Were all of the necessary assumptions/conditions met in this study? a. No, the randomization condition was not met
b. Yes No, the 10% condition was not met
c. No, the nearly normal condition was not met

International calls require the use of a country code. many country codes a 3-digit numbers. country codes do not begin with a 0 or 1. there are no restrictions on the second and third digits. how many different 3-digit country codes are possible?
