You are working in the IT department at a small company and need to pick either Rackspace or Amazon as a cloud based service provider based in part on the reliability. An intern examines publicly available data from IWGCR and other sources producing the table below.

	Microsoft Azure			Rackspace
	Mean (min)	Variance	Number of Observations	Mean (min)	Variance	Number of Observations
Outage duration:	467.56	1100.18	40	493.85	872.58	18

(a) Is it possible to determine which service provider has shorter outages?

(b) How would additional data points affect your decision?
