One of the symptoms of acute anxiety is increased heart rate. A researcher would like to determine if relaxation training will affect the heart rate for those who suffer from this type of anxiety. Prior to training, each participant had their heart rate measured during an anxiety episode. Participants then received relaxation training, and their heart rate was measured again during their next anxiety attack. Use a two-tailed test, at the= .05 level.

The data obtained are as follows:

Subject Measurement 1 - BPM Measurement 2 - BPM

A 98 93

B 94 90

C 96 95

D 91 92

E 97 95

F 97 91

G 95 92

H 97 93

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

B- Report the following values

MD= ________SS= ________s2= ________D= ________D2= ________

C- State the H0and H1in symbols.

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

E- Report the estimated standard errorandobtainedt-statistic value.

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

G- Write the findings of this decision in symbols as per appropriate APA notation.

H- State the decision that would be made if this test were run at the= .01 level of significance.
