SPSS ANALYSIS
a) Check if heartrate = 80 bps.
Hypothesis Testing:
0) Normality check:
Analyse>> descriptive statistics >> explore
P= 0.814 >> which is more than a.
The variable is normally distributed.
1) Statement of Hypotheses
Null Hypothesis (H0): heartrate = 80 bps.
Alternative hypothesis (HA /H1): heartrate ≠ 80 bps >> two tailed test.
2) Level of Significance:
α = 0.05
3) Test Statistic
One sample t-test
4) Critical Region/Rejection Region
Reject Ho if p ≤ α
5) Computation
Analyse >> compare means>> one-sample t test
6) Result & Conclusion
P – value is less than α Conclusion: Heart rate shows statistical significant difference from hypothetical heartrate = 80 bps.
