Question

5. You are interested in comparing the average, systolic blood pressure of women athletes during intense exercise to the healthy, systolic blood pressure of the general population when at rest (i.e. not during exercise) (µ = 120).

Because exercise increases systolic blood pressure, you predict that the average, systolic blood pressure for women athletes during exercise will be significantly greater than the systolic, resting blood pressure (µ = 120). Your alpha level is 0.05. (50 points)

Note: Your test value in SPSS is 120 – not zero.

Sample of women athletes:

Systolic Blood Pressure
125
133
120
113
124
131
123
128
124
120

1. Are you running a one-tailed or two-tailed test?

2. Write your alternative and null hypotheses.

3. Which statistical analysis will you use to run your test (e.g. one-sampled t-test, an independent-samples t-test, a paired t-test, or chi-square test)?

4. Run your statistical analysis using SPSS. Write your conclusions.

(Remember, if you are running a one-tailed test, your alpha value is located in one-tail, meaning your p-value needs to be less than 0.05 to reject the null hypothesis.

If you are running a two-tailed test, your alpha value is divided in half, meaning your p-value needs to be less than 0.025 to reject the null hypothesis)
