Test the following hypotheses for a multinomial probability distribution by using the x^2 goodness of fit test.
Ho:Pa=0.2, Pb=0.4, Pc=0.4
Ha: The probabilities are not
: Pa=0.2, Pb=0.4, Pc=0.4
A sample of size 200 yielded 50in category A, 110 in category B, and 40 in category C.
Use a=0.01 and test to see whether the probabilities are as stated in Ho.
A: use the p-value approach. x^2=
P value:
Conclusion:
b. Repeat the test using the critical value approach
x2.01=
x2=
