Solution:
Expected frequency= 6.67
Obseved frequency (fo) Expected frequency (fe) (fo-fe)^2/fe
5.00 6.67 0.42
10.00 6.67 1.67
5.00 6.67 0.42
2.50
H0:Observed pattern follows expected pattern
H1: Observed pattern does not follow expected pattern
Critical Value: (Use Table or use Excel)
=5.991
DEGREE OF FREEDOM=2, ALPHA =0.05
Test Statistics : Refer table and formula above
=2.50
Decision and Conclusion:
Since test statistics lies in the region bound by critical value, we cannot reject null ...
