Week 3   Paired T-proof and ANOVA

For this week's achievement, intermittently be sboard to nartrounce the inoperative and be-undetermined hypotheses and use alpha = 0.05 for our resolution value in the repudiate or do not repudiate resolution on the inoperative conjecture.

1.  Many companies observe the gradation midaim to be the "dispense trounce" - the remuneration insufficiencyed to employ a new employee.

Does the crew, on mediocre, pay its corporeal employees at or overhead the dispense trounce?                                                                                                                                                                                          Salary   Midaim    Diff

Use the axioms columns at the direct to set up the paired axioms set for the dissection.

Null Hypothesis

Alt Hypothesis

Statistical proof to use:

What is the p-value:

Is P-value < 0.05 (one bulk proof) or 0.25 (two bulk proof)?

Do we REJ or Not repudiate the inoperative?

If  the inoperative conjecture was repudiateed, what is the property extent value:

If fitted, what is the aim of property extent measure:

Interpretation of proof results:

Let's face at some other factors that dominion wave pay - direction(degree) and employment ratings.

2.  Last week, we institute that mediocre employment ratings do not disagree natant males and females in the population.

Now we insufficiency to see if they disagree natant the gradations. Is the mediocre performace rating the corresponding for all gradations?

(Assume antagonisms are similar over the gradations for this ANOVA.)

The rating values exclusive by gradation keep been placed in columns I - N for you.

Null Hypothesis: Ho: instrument similar for all gradations

Alt. Hypothesis: Ha: at moderationest one moderation is unequal

Place  B17 in Outcome place box.

Interpretation of proof results:

What is the p-value:

Is P-value < 0.05?

Do we REJ or Not repudiate the inoperative?

If  the inoperative conjecture was repudiateed, what is the property extent value (eta squared):

Meaning of property extent measure:

What does that resolution moderation in stipulations of our similar pay question:

3.  While it appears that mediocre salaries per each gradation disagree, we insufficiency to proof this self-assertion.

Is the mediocre remuneration the corresponding for each of the gradation flattens?

Use the input board to the direct to catalogue salaries inferior each gradation flatten.

(Assume similar antagonism, and use the dissection toolpak discharge ANOVA.)

Null Hypothesis:

Alt. Hypothesis:

Place  B51 in Outcome place box.

Interpretation of proof results:

What is the p-value:

Is P-value < 0.05?

Do we REJ or Not repudiate the inoperative?

If  the inoperative conjecture was repudiateed, what is the property extent value (eta squared):

If fitted, what is the aim of property extent measure:

Interpretation:

4.  The board and dissection under demonsttrounce a 2-way ANOVA after a while replication.  Please expone the results.

Ho: Mediocre compas by gender are similar

Ha: Mediocre compas by gender are not similar

Ho: Mediocre compas are similar for each extent

Ha: Mediocre compas are not similar for each extent

Ho: Interaction is not significant

Ha: Interaction is significant

Perform dissection:

Interpretation:

For Ho: Mediocre compas by gender are similar Ha: Mediocre compas by gender are not similar

What is the p-value:

Is P-value < 0.05?

Do we REJ or Not repudiate the inoperative?

If  the inoperative conjecture was repudiateed, what is the property extent value (eta squared):

Meaning of property extent measure:

For Ho: Mediocre compas are similar for all extents  Ha: Mediocre compas are not similar for all gradations

What is the p-value:

Is P-value < 0.05?

Do we REJ or Not repudiate the inoperative?

If  the inoperative conjecture was repudiateed, what is the property extent value (eta squared):

Meaning of property extent measure:

For: Ho: Interaction is not significant Ha: Interaction is significant

What is the p-value:

Is P-value < 0.05?

Do we REJ or Not repudiate the inoperative?

If  the inoperative conjecture was repudiateed, what is the property extent value (eta squared):

Meaning of property extent measure:

5.  Using the results up thru this week, what are your conclusions environing gender similar pay for similar achievement at this aim?
