The computer operations department had a business objective of reducing the amount of time to fully update each subscriber’s set of messages in a special secured email system. An experiment was conducted in which 40 subscribers were selected with four difference messaging systems and two connection media types used. The subscribers were randomly assigned so that there were five subscribers in each of the eight combinations of the two factors – messaging system and media used. The updates time are as follows.

Completely analyze these data and write a report to the team that indicates the importance of each of the two factors and/or the interaction between them on the update time. Hint: Use Two-Way ANOVA spreadsheets.

What Do People Do on Facebook?
In a survey of 2255 US adults, we learn that 970 of the respondents
use the social networking site Facebook.1Of the 970
Facebook users, the survey shows that on an average day:
• 15% update their status
• 22% comment on another’s post or status
• 20% comment on another user’s photo
• 26% ‘‘like” another user’s content
• 10% send another user a private message.
1Hampton, K., Goulet, L., Rainie, L., and Purcell, K.,
‘‘Social Networking Sites and Our Lives,” Pew Research Center, June
16, 2011.
(a) For each of the bulleted activities, find a 99% confidence
interval for the proportion of Facebook users engaging in that
activity on an average day.
Round your answers to three decimal places.
| Bulleted Activities | Confidence Interval | |||
| Update status: | to | |||
| Comment on another’s post or status: | to | |||
| Comment on another user’s photo: | to | |||
| ‘‘Like” another user’s content: | to | |||
| Send another user a private message: | ___________________________ | to | ____________________________ | |
(b) Is it plausible that the proportion commenting on another’s post or status is the same as the proportion updating their status?
Yes or No?
