Question

For this discussion forum, refer to the **Excel file
Discussion 8-1 Data Set** that contains information on the
following:

In the healthcare profession, you will be presented with
**ANOVA tables** using different forms of technology
(i.e. SPSS, Minitab, Excel, SAS, etc.). An important part of the
analysis is to take the results from the ANOVA and make the proper
inferences from it.

- Identify the worksheet (tab) that matches
**the first letter of your LAST name**(i.e., if your last name were “Fudd” you would use the data from the “F” tab).*This will be the source data you will use to answer your remaining questions for this initial post.* - From your ANOVA table: What is the
**test statistic**? - From your ANOVA table: What is the
**p-value**? - Assuming a
**level of significance at 0.05**, would you**reject**or**fail to reject**your null hypothesis? Explain how you came to this conclusion (i.e., either use the test-statistic/critical value or p-value to support your claim).

For this discussion forum, refer to the Excel file
Discussion 9-1 Data Set that contains information on the
following:
Identify the worksheet (tab) that matches the first
letter of your LAST name (i.e., if your last name were
“Fudd” you would use the data from the “F” tab). This
will be the source data you will use to answer your remaining
questions for this initial post.
From your source data: What is the linear correlation
coefficient?
Using the linear correlation...

Managers at all levels of an organisation need adequate
information to perform their respective tasks. One study
investigated the effect the source has on the dissemination of
information. In this particular study the sources of information
were a superior, a peer and a subordinate. In each case, a measure
of dissemination was obtained, with higher values indicating
greater dissemination of information. To verify whether the source
of information significantly affects dissemination, you perform the
ANOVA test. The following table partially...

fleet manager wanted to determine the best replacement tires for
their corporate automobiles. He selected six tire-types and had a
set of each of them installed randomly on 23 selected automobiles.
He then recorded the mileage when the tires came due for
replacement. Use the Excel output below to analyze the data. Are
there differences in life-time mileages of tires, at the five
percent significance level?

You want to compare the means of several different groups to
determine if all are equal or if any are significantly different
from
the rest. For instance on the Insurance file you may wish to see
if there is any significant differences in satisfaction among
individuals with different levels of education. You have
rearranged the Insurance File to give the following:
College degree
Graduate degree
