Question

How did the decisions from the hypothesis ?compare to whether or not the 95% or the 99% confidence interval contained 0? Answer this question in two or three sentences.

At 0.05 significance level
Decision Rule : Reject null hypothesis if p< 0.05
Conclusion: As 0.025688 < 0.05 therefore null hypothesis will be rejected that means there is significant
difference between the population mean of before and after.
At 0.01 significance level
Decision Rule: Reject null hypothesis if p< 0.01
Conclusion: As 0.025688 > 0.01 therefore null hypothesis will not be rejected that means there is no significant
difference between the population mean of before and after.
