A researcher is testing the effect of a new cold and flu medication on reaction time. A sample ofn= 9 students is obtained and each student is given the normal dose of the medicine. Thirty minutes later, each student's reaction time is measured. The scores for the sample averagedM= 211 milliseconds withSS= 1152. Reaction time for students in the regular population averages= 200 milliseconds. Set the level of significance at an= .05, using a two-tailed test.

A- Whichtstatistic, (single-sample, independent-measures, or repeated-measures), should be used with this data?

B- State the H0and H1in symbols, based on a two-tailed test.

C- State thet-score value(s) that defines the critical region(s).

D- Report the sample variance, estimated standard error, and obtainedt-statistic value.

E- State the decision that should be made based on these results

F- Write the results / decision in apa symbols.

G- State what decision would be made using an= .01, for a two-tailed test.
