Factor = Winter, Spring, Summer, Fall

Assign numbers to these groups (Winter = 1, Spring = 2, Summer = 3, Fall=4)

Brand A = 1
Brand B = 2
Brand C = 3
Brand D = 4

Correction H(1): μ c ≠ μ s

t obtained .66
Decision: Fail to reject H(0)

Perfect! Thank You! :)

Convert 134 to z form:

z = (134 - 125)/10

Once you have z, read the area in the standard normal curve to the RIGHT of z.

2-1. The mean of the sampling distribution of sample mean differences is equal to 0.

2-3. The sampling distribution of sample mean differences has a standard deviation equal to σ_d. An estimate of this standard deviation is symbolized as s_d.

thank you it was driving me crazy

Assignment 5

3-3. r = .941 which is strong

3-4 Use the regression equation Y' = a + bX and substitute 700 for X (since all raw data in the problem is given in thousands).

Answer: 46.07

3-5 square r or .941^2 = .941 X .941 or .885

Yes. It is ANOVA.

Please follow the steps displayed here:

Please check older blogs and I believe you will find the answer.

Example:

To get the symbol μ, type the following string of text:

& m u ;

But you MUST TYPE ALL 4 CHARACTERS WITH NO SPACES

I tried this several times and no symobls ever showed up

Then you must be doing something incorrectly.

Always start with the & character.

Always end with the ; character.

In between these two characters, there will be a string of other characters, for example:

mu
sigma
plusmn

For the above strings, place an & in front and a ; at the end (no spaces).

When you save your work, you will see the symbol displayed correctly.

Yes I was having trouble with that myself

The blog explains how to put them into your journal.

Here's how to get them.

Type & s i g m a ; (I've included spaces here to show you the exact string of characters needed BUT NO SPACES when you type it) to get σ. PLEASE NOTE: You MUST include the & and the ;

Type & m u ; (I've included spaces here to show you the exact string of characters needed BUT NO SPACES when you type it) to get μ. PLEASE NOTE: You MUST include the & and the ;

Type & s u m ; (I've included spaces here to show you the exact string of characters needed BUT DO NOT include SPACES when you type it) to get ∑. PLEASE NOTE: You MUST include the & and the ;

In other words, the & and ; are part of the string.

& s i g m a ; (please remove the spaces) = σ

& m u ; (no spaces please) = μ

& s u m ; (no spaces please) = ∑

& a l p h a ; (no spaces please) = α

& n e ; (no spaces please) = ≠

& p l u s m n ; (no spaces please) = ±

I did that on assignment 2 and a question mark and a diamond showed up instead of the symbol.
