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.
