a.
Answer to Problem 54E
Yes, data set is providing sufficient evidences.
Explanation of Solution
Given:
SAS output is:
Calculation:
The null and alternative hypotheses for the provided case are:
The test statistic is computed as:
The degree of freedom is calculated as:
The p-value:
In this case,
The null hypothesis could be rejected which is showing the sufficient evidences for the claim.
b.
To interpret: The P -value in the context of problem.
b.
Explanation of Solution
The P -value is 0.0247 which implies that if all the means of population are same, the probability of having a sample mean difference or above is 0.0247.
