An Internet service provider is interested in testing to see if there is a difference in the mean weekly connect time for users who come into the service through a dial-up line, DSL, or cable Internet. To test this, the ISP has selected random samples from each category of user and recorded the connect time during a week period. The following data were collected. Click the icon to view the ISP data. Assuming that the test is to be conducted at a 0.01 level of significance, what would the critical value be for this test?
