The effective life of insulating fluids at an accelerated load of 35 kV is being studied. Test data have been obtained for four types of fluids. The results from a completely randomized experiment were as follows:

Fluid Type	Life (in h) at 35 kV Load
1	17.6	18.9	16.3	17.4	20.1	21.6
2	16.9	15.3	18.6	17.1	19.5	20.3
3	21.4	23.6	19.4	18.5	20.5	22.3
4	19.3	21.1	16.9	17.5	18.3	19.8

A.What is the number of replicates in these experiments?

B.What is the response variable (output)?

C.What is the factor?

D.many factors do we have for this problem?

E.How many levels are considered for the factor?

F.What test should be used to know whether all 4 different batches have the same effect on mean of calcium content?

G.Using the Minitab software and running a proper test on the aforementioned data, do them different four batches have the same effect on calcium content?

H.What is the null hypothesis (H0) for this problem?

i.What is the alternative hypothesis (H1 or H^A) for this problem?

J.After running the proper test, what is P-value for this problem?

K.What value did you choose for the error type I (significance level) for this problem?

L.What is confidence level?

M.After solving the question, what value did you get for the F test statistic?

N.What value did you get for sum of square treatment (source of variation between groups due to factor)?

O.What value did you get for sum of square error (source of variation within group due to error)?

P.Using Minitab, Plot the residuals versus the predicted response. Construct a normal probability plot of the residuals. What information is conveyed by these plots?
