3c) Using an appropriate statistical test, determine if, on average, there is a difference in initial systolic blood pressure (BPXSYes) between those people reducing fat in their diet and those who aren’t (BPXSno). In performing the test, include:
State appropriate hypotheses (define any symbols used).
Using an appropriate formula and showing all working, calculate a suitable test
statistic. You can use SPSS to calculate the means and standard deviations but
the test statistic should be calculated by hand.
Without using SPSS, calculate the P-value of this test (clearly define the degrees
of freedom used in calculating this value).
Interpret the P value and write a meaningful conclusion to answer the above
BPXSYes MEAN - 128
BPXSYes STD DEV - 21.1801
BPXSno MEAN - 120
BPXSno STD DEV - 16.527
SAMPLE SIZE - 200
