Problem: Does Cell Phone Use while Driving Impair Reaction Times?

You work for the National Traffic and Safety Board (NTSB). You are placed in charge of investigating this problem. Using students at a local university, you design an experiment using a machine that simulates driving situations where at irregular periods a target flashed red or green. Participants were instructed to press a "brake button" as soon as possible when they detected a red light. Two driving conditions were arranged. In one, students listened to a radio broadcast while simulating driving; in the other, students carried out a conversation on a cell while speaking with someone in a separate room. For each participant, the experiment measured their mean response time over all trials (i.e., exposures to simulated red lights). The response times were measured in milliseconds. Being overly cautious regarding making a Type 1 error, the NTSB has asked you to use 0.01 (1%) as alpha for any test.

Data: The data, in an Excel spreadsheet, represents the data collected and is formatted in different ways allowing for various statistical methods to be applied. Your requirements:

1. Write report on your findings and outputs briefly. And describe why to use this method and why not the others. And also describe and briefly explain the results.
