Question
You are conducting a Goodness of Fit hypothesis test for the claim that the 4 categories occur with the following frequencies:
H0 : pA=0.3; pB=0.2; pC=0.2; pD=0.3
Give all answers as decimals rounded to 3 places after the decimal point, if necessary.
Complete the table:
Category | Observed Frequency |
Expected Frequency |
---|---|---|
A | 30 | Correct |
B | 25 | Correct |
C | 20 | Correct |
D | 34 | Correct |
What is the chi-square test-statistic for this data?
Test Statistic: χ2=
Correct
For a significance of level alpha = 0.01, what is the chi-square critical value?
Critical Value: χ2=
Incorrect
What would be the decision of this hypothesis test?
- Fail to reject H0
- Reject H0
Correct
Remember to round all answers to 3 places after the decimal point, if necessary.
