Question

A marketing firm needs to replace its existing network provider and is considering three different providers. A primary consideration is the amount of system downtime. The following table contains the amount of network downtime (in hours) for the last five months for each network provider.  The p-value for the test is ________.
A) less than 0.01 
B) between 0.01 and 0.05 
C) between 0.05 and 0.10 
D) greater than 0.10

To determine the p-value, we need to conduct an ANOVA test. Using a statistical software, the result of the ANOVA test shows a p-value of 0.0038.

Since the p-value is less than 0.01, we can reject the null hypothesis and conclude that there is a significant difference in the amount of network downtime among the three providers.

Therefore, the marketing firm should consider choosing the provider with the least amount of system downtime.
