hello i need help answering the following questions !

Imagine you are a researcher who is interested in studying whether sleep deprivation leads to increased reaction times (i.e., being slower) when driving. You randomly select a sample of 30 licensed drivers. Fifteen participants are randomly assigned to get 5 hours of sleep for 3 consecutive nights. The other 15 participants are randomly assigned to get 8 hours of sleep for 3 consecutive nights. For the purposes of this Assignment, assume that all participants sleep exactly the required amounts. After the third night, all participants take a driving simulation test that measures their reaction times.

Enter the following dataset into SPSS, then conduct the appropriatet-test to answer the questions and determine if sleep time is related to reaction time. Be sure to fully explain the rationale for your answer to each question.
