DIASTOLIC BLOOD PRESSURE BETWEEN FEMALES WHO SMOKE AND FEMALES WHO DON'T

T Confidence Intervals

Variable N Mean StDev SE Mean 95.0 % CI

Female N 12 65.50 9.79 2.83 ( 59.28, 71.72)

Female S 8 72.88 14.50 5.12 ( 60.75, 85.00)

-Female nonsmokers have a lower median and interquartile range as far as the box plots go, and a lower mean as far as the t-intervals go.

-Female smokers have lower minimum blood pressure, and a very high interquartile range.

Looking at these graphs alone, it appears that the smokers have higher blood pressure readings than the non-smokers. However, there are some outliers that show that the data is not normally distributed. More samples could help tell if blood pressure readings between non-smokers and smokers are significantly different.
