Question
*2. Can repressed anger lead to higher blood pressure? In a hypothetical study, 16 col- lege students with very high repressed anger scores (derived from a series of question- naires taken in an introductory psychology class) are called in to have their blood pres- sure measured. The mean systolic blood pressure for this sample (X) is 124 mmHg. (Millimeters of mercury is the standard unit for measuring blood pressure.) If the mean systolic blood pressure for the population is 120 with a standard deviation of 10, can you conclude that repressed anger is associ- ated with higher blood pressure? Use alpha = .05, two-tailed.Explanation / Answer
We can use here One sample Z test as Population Standard deviation is given
One-Sample Z
Test of mu = 120 vs not = 120
The assumed standard deviation = 10
N Mean SE Mean 95% CI Z P
16 124.00 2.50 (119.10, 128.90) 1.60 0.110
Here P-value 0.11 which is more tha alpha 0.05 so we do not reject the null hypothesis and we conclude that Anger is not associated with higher Blood pressure.
Hope this will b ehelpful. Thanks and God Bless You:-)
