Concept explainers
To explain: The P-value is lower than 0.001.
Answer to Problem 1CS
Solution: The smaller P-value shows that there is a difference between the amount of the time of socialization that is reported by the two groups.
Explanation of Solution
The obtained P-value is less than 0.001, which is less than the desired significance level. That is, the null hypothesis will be rejected in the provided scenario. The acceptance of the null hypothesis shows that there is no difference between the two groups of college freshmen, while one group is used to socialize at least 16 hours in each week and the other group is used to socialize for 5 dedicated hours.
As the null hypothesis is not accepted, it can be said that there is a difference between the amount of the time of socialization, which is reported by the two groups, and the difference cannot occur due to some random chance. The lesser P-value indicates that the test provides a statistically significant result.
