The hours of sleep for both group of students are stored in EarlyClass.xlsx. Download and open this file into Excel. Use Excel to undertake a suitable test to address the research question below.

Is there a difference between the average hours of sleep for students with early classes versus students with no early classes?

Answer the following questions by choosing the most correct option or typing the answer:

1. (1 mark) The most appropriate test for these data is: AnswerA two-sample t-testA paired t-test

2. (1 mark) The normality assumption seems reasonable because: Answerboth sleep hours for students with early classes and no early classes may be drawn from normal distributions.the differences between sleep hours of students with no early classes and with early classes may be drawn from a normal distribution.

3. (1 mark) The assumption of equal variance seems reasonable because: Answercomparative boxplots suggest the variation in the two populations could be the same.comparative boxplots suggest the variation in the two populations is different.

For the remaining questions you may assume that any relevant assumptions have been met.

4. The absolute value of the test statistic is equal to (type your answer with 3 dp)  Answer

5. (1 mark) The degrees of freedom is equal to (type your answer as an integer)  Answer

6. (1 mark) The p-value is larger than 0.05 Answertruefalse

7. The test shows that the average hours of sleep was Answersignificantly greater for students with no early classes than for students with early classes.significantly greater for students with early classes than for students with no early classes.not significantly different for students with no early classes and for students with early classes.
