Step 1

Let *µ*_{1}, *µ*_{2} and *µ*_{3} are the population mean of Machines A, B and C.

The hypothesis can be constructed as:

Null hypothesis, *H*_{0}:* µ*_{1}=* µ*_{2}=* µ*_{3}

Alternative hypothesis, *H*_{a}: (At least two *µ*_{i}’s are not equal.)

From the provided information, the number of treatments (*k*) = 3

Sample size (*n*_{1}=* n*_{2}=* n*_{3}) = 5

The sample mean of all treatments can be obtained as:

Step 2

The total number of observations can be obtained as:

*N* = *n*_{1}+* n*_{2}+* n*_{3}

= 5+5+5

= 15

The grand total can be obtained as:

Step 3

The total sum of square c...
