Inference Statistics

Explanation of the Statistics Procedures Used

This a matched-pair T Statistics is to observe the edit usage intervals of Ksyrie and Yeahsoo.

H0 (null hypothesis): the difference between Ksyrie and Yeahsoo edits equal 4 or more hours.
Ha (alternative hypothesis): the difference between Ksyrie and Yeahsoo edits is less than 4 hours.

For Ksyrie, from mid-March to mid-February 2007, for Yeahsoo, mid-March 2007to early-December 2006; for each day, earliest and latest times of edit were used. For days with only one edit, the time was repeated.
60 samples per user were used (total of 120).
To convert minutes to hours, this site was used.
Data input and calculations were done on Ti-84 Plus Silver Edition.

Statistics on intervals of user activity	Ksyrie[1]	Yeahsoo[2]
Mean X	13.01	15.14
Sx/σx	8.506/8.435	6.741/6.684
MinX/MaxX	.05/23.93	0/23.9167
t & p (2-Sample T Test =/=)	-1.77854 & .040234	Enough data to reject the H0, and accept Ha. P-value of 0.040234 is much less than the standard 0.05 for 95% confidence level. The test proves 95% that Ksyrie's and Yeahsoo's edits are within 4 hours of each other.
