Perhaps I MISUSED Minitab….

Power and Sample Size

2-Sample t Test

Testing mean 1 = mean 2 (versus <)

Calculating power for mean 1 = mean 2 + difference

α = 0,05  Assumed standard deviation = 400

Results

Difference -600
Sample Size 10
Target Power 0.92
Actual Power 0.942864
The sample size is for each group.

I used mu2-m1=600

@Darth

Using Minitab, at “Power and Sample Size” I think I found that 10+10 items should give at list 90% power for the differences to be assessed…. IF I used Minitab properly!!! (at “Power and Sample Size”)…………

It could be that the “non-rejection of the H0” could depend on the methods used…

YOU SAY:

I am trying to find degrees of freedom, the formula that I know

df = n− 1

THIS FORMULA is NONSENSE in your case

From a sample, whose population is assumed to follow a Normal Distribution, taken for 30 days at 60 degrees or more an average of 13.6 pots per day were sold with a Standard Deviation of 0.7 pots.

@rbutler

Your last reply with the statement about “”””the PBV method of scientific discourse (Proof By Volume)””” made me think that we have different ideas about THEORY and SCIENTIFICNESS.

For me THEORY is

• ·         The set of all LOGIC Deductions
• ·         Drawn
• ·         From Axioms and Postulates
• ·         Which allow t…

MANY “discussants” in ISixSIGMA write HIDDEN by their nicknames ….

Could you please tell them to give information about their publications SO THAT I CAN READ them …. and I will come back to you and them?

WILL THEY do it?

Let’s wait and see….

@David007

You are an “expert”

IGNORANT, INCOMPETENTS and PRESUMPTUOUS running in the DISquality Vicious Circle…

YOU DO NOT realise that good ideas DO NOT depend on WHERE they are PUBLISHED!!!!

YOU DO NOT know the THEORY.
