# Question: 3c using an appropriate statistical test determine if on average...

###### Question details
• 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:

1. State appropriate hypotheses (define any symbols used).

2. 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.

1. Without using SPSS, calculate the P-value of this test (clearly define the degrees
of freedom used in calculating this value).

2. Interpret the P value and write a meaningful conclusion to answer the above
question.

BPXSYes MEAN - 128

BPXSYes STD DEV - 21.1801

BPXSno MEAN - 120

BPXSno STD DEV - 16.527
