Homework Answers
Ans:
Total number of observations=17+26+8+25+14+6=96
Expected count=pi*96
(pi is the percentage for respective colur)
| Observed(O) | Expected(E) | (O-E)^2/E | |
| Green | 17 | 14.4 | 0.469 |
| Orange | 26 | 20.16 | 1.692 |
| Yellow | 8 | 13.44 | 2.202 |
| Blue | 25 | 23.04 | 0.167 |
| red | 14 | 12.48 | 0.185 |
| Brown | 6 | 12.48 | 3.365 |
| Total= | 96 | 96 | 8.080 |
Chi square score=8.080
df=6-1=5
p-value=CHIDIST(8.080,5)=0.1519
As,p-value>0.05,we fail to reject H0.The color distribution is the same as reported.
