A software developer is interested
in finding what the best color theme should be for an engine
diagnostic program for the flight line. He is considering three
different color themes (red, green, or blue). To determine which is
preferred by his users he invited 60 participants to view the three
different designs (colors). He then asked them which one they liked
best. The table below presents the number of times each design was
chosen by the participants.
|
Red |
Green |
Blue |
|
14 |
18 |
28 |
(a) Use appropriate words and
statistics to describe the statistical results. Based on this data
which design should he use?
Here is what I have so far –
Chi-Square test:
| Statistic | DF | Value | P-value |
|---|---|---|---|
| Chi-square | 2 | 2.49742 | 0.2869 |
so to properly notate the answer: X2(2, N = 60) =
5.2, p = .074 is this correct?
I am assuming that the design chosen is red because it has the
highest percentage chosen at 58.33%? I guess i dont understand what
the question is asking.
Thanks
