22 DS3 Non-Simplex Outages are statistically shorter in 2015 compared with 2014 (using a Mann-Whitney test)

23 E911 Outages are statistically longer in 2015 compared with 2014 (using a Mann- Whitney test)

24 The duration of wireline outages is statistically unchanged from 2014 to 2015 (using a Mann-Whitney test)

25 The duration of wireless outages is statistically unchanged from 2014 to 2015 (using a Mann-Whitney test)

26 Non-DS3-Simplex Outages Data from 1/12 thru 9/15 Conclusion: Non DS3- Simplex Outages are unchanged in duration from 1/12 to 9/15 DS3-Simplex Events Only Data from 1/12 thru 9/15 Conclusion: DS3-Simplex Events are unchanged in duration from 1/12 to 9/15 Rank Correlation of duration with date is and is not significant at the.01 level Rank Correlation of duration with date is and is not significant at the.05 level
