In a survey conducted among a random sample of college students, participants were asked, “How many hours per week do you use the Internet?” Sample sizes and average responses by race/ethnic group are given below. Assume sample standard deviations were as shown in the table.

Use one-way analysis of variance to determine if there is sufficient sample evidence to reject a “no difference in population mean Internet times” null hypothesis at the 5% significance level.
