She took 3 of each brand and determined their maximum downhill speeds. The results are presented in miles per hour in the table. Complete all the missing values in the above table and fill in the blanks Use alpha = 0.01 to determine if their is my significant difference among the means (state proper hypothesis)

Solution

Since F_obs>F_0.01,3,8=F_cr,we reject H₀ at 1% level of significance and we can conclude that there is significant difference among the means.
