problem-11.1

problem-11.1  The data is stored so that the function oneway.test() is straightforward to use:
> names(morley)
[1] "Expt"  "Run"   "Speed"
> oneway.test(Speed ~ Expt, data=morley)

        One-way analysis of means (not assuming equal variances)

data:  Speed and Expt
F = 3.006, num df = 4.00, denom df = 47.04, p-value = 0.02738
    
The small p-value is consistent with the impression left after considering side-by-side boxplots that the centers are not the same.
