Statistics: Pulse Rate Means Assignment
H0 : µ = 75
H1 : µ < 75.25
α = 0.05
95% Confidence Interval: 75 ± 3.2 (71.8 to 78.2)
P value= 0.5613
Since the P-value 0.5613 is greater than the significance level 95%, null hypothesis should not be rejected.
2)
H0: µ = µ 1 - µ 2 = 0
H1: µ< µ 1 - µ 2
α = 0.05
95% Confidence Interval: from -4.6433 to 4.5433
P value= 0.9825
The difference is considered to be not statistically significant, therefore the null hypothesis should not be rejected.
3)
H0: µ = µ 1 - µ 2 = 0
H1: µ< µ 1 - µ 2
α = 0.05
95% Confidence Interval: From -9.0257 to -2.4743
The two-tailed P value equals 0.0008
Therefore, the difference is considered to be statistically significant. By this, the null hypothesis should be rejected.

To complete the above calculations, I have used T-scores, since sample size was below 30. Comparing to Z-score, results would be somewhat different, while T-score would be somewhat more …
