Tasks 0 & 1
This problem has the data set for you to to use for THQ#2.  Copy the values from the table below into SPSS.  (If you encounter any problems, contact your instructor right away.)  These online problems are to be done in conjunction with the instructions for the tasks on the paper assignment.

Here is the proposed scenario for this data.  (Remember, you are welcome to propose an alternate scenario in your write-up, but the dependent variable for all analyses must be the same.)  For all problems, please use a significance level of $\displaystyle \alpha={0.05}$.

The data reports final exam scores for 4 groups of students.  Groups 1 and 2 had recitation sections on Mondays; groups 3 and 4 had recitation sections on Fridays.  The professor generally believes that the exam performance is comparable across days (and sections).

Please report the following univariate sample statistics after running the requested analyses in SPSS.  (Report all answers accurate to 2 decimal places.)

Overall sample statistics:
For the entire sample (treated as one large group), what were the mean and standard deviation?
overall mean:  $\displaystyle {M}=$
overall standard deviation:  $\displaystyle {S}{D}=$

Disaggregated sample statistics (by day, not by group):
Report the following sample statistics and 95% confidence interval for the Monday sessions (combining the appropriate groups into one larger group).
sample mean:  $\displaystyle {M}_{{\text{Monday}}}=$
sample standard deviation:  $\displaystyle {S}{D}_{{\text{Monday}}}=$
confidence interval:  $\displaystyle <\mu_{{\text{Monday}}}<$

Report the following sample statistics and 95% confidence interval for the Friday sessions (combining the appropriate groups into one larger group).
sample mean:  $\displaystyle {M}_{{\text{Friday}}}=$
sample standard deviation:  $\displaystyle {S}{D}_{{\text{Friday}}}=$
confidence interval:  $\displaystyle <\mu_{{\text{Friday}}}<$
