You hypothesize that younger adults are more stressed than all other age groups. You compare stress levels between three groups: Young adults, middle aged adults, and older adults. You collect data in 30 individuals and your data is as follows: Young Adults Middle Aged Adults Older Adults 100 100 50 50 95 56 84 95 55 70 80 85 75 75 35 85 60 60 62 55 30 30 100 25 100 64 75 100 78 60 The between group sum of squares for this sample is 4206.07. The within group sum of squares for this sample is 10720.9. What is the f-ratio for this data set? Round to the tenths place.

Question

You hypothesize that younger adults are more stressed than all other age groups. You compare stress levels between three groups: Young adults, middle aged adults, and older adults. You collect data in 30 individuals and your data is as follows:

Young Adults	Middle Aged Adults	Older Adults

85	60	60
62	55	30
30	100	25
100	64	75
100	78	60

The between group sum of squares for this sample is 4206.07. The within group sum of squares for this sample is 10720.9. What is the f-ratio for this data set? Round to the tenths place.
