A researcher with the Ministry of Transportation is commissioned to study the drive times to work {one-way] for US. cities. The underlying hypothesis is that average commute times are different across cities. To test the hypothesis. the researcher randomly selects six people from each of the four cities and records their one-way commute times to work. Refer to the below data on one-way commute times (in minutes) to work. Note that the grand mean is 36.625. as 667 Based on the sample standard deviation, the one-way ANOVA assumption that is likety not met is Multiple Choice 0 the populations are normally distributed. a the population standard deviations are assumed to be equal
