A racing team runs an experiment to test out their new car wifi-technology that transmits data about the car as it is pulling into the pit lane. In particular they want to know that the average download speeds of data is greater than 1 GB per second so that the pit crew gets all the data they need from the car in time. The team runs ten independent experimental runs to test the download speed by simulating race conditions for pit lane entry and data transmission. Which answers are true?

Answers

1. They should use the ANOVA model for analysis because there are 3 or more experimental runs.

2. The hypotheses of the analysis can be written as: H_0=mu_speed = 1 GB/s vs H_a: mu_speed > 1 GB/s

3. The key hypotheses can be analyzed using a one sample t-test if assumptions are met.

4. This experiment follows the principal of replication because it repeats the same experimental run 10 times.
