Question
In a chi-square test for goodness of fit, the term observed frequency re A. the frequencies found in the sample data B. the frequencies found in the population being examined C. the frequencies computed from the null hypothesis D. the frequencies that are hypothesized for the population being esamined . For the chi-square test for goodness of fit, what is the value of degrees of freedn frite.Sw categories and a sample of n-100 A. 3 B. 4 C. 96 D. 99 3. When we carry out a chi-square test for independence, the null hypothesis states that the row variable and column variable A. àre mutually exclusive. B. form a contingency table with r rows and c columns C. have (r-1) and (c-1) degrees of freedom wherer-number of rows andc-number of columm D. are statistically independent. E. are normally distributed. 4. When using the chi-square goodness of fit test with multinomial probabilities, the rejection d null hypothesis indicates that at least one of the probabilities is not equal to the value stated in hypothesis A. True B. False 5. When using the chi-square goodnes of fitest,if the value of the chi-square statisticis we reject the null hypothesis. A. True B. FalseExplanation / Answer
1.
A) The frequencies found in the sample data
2.
A) 3
DF = 4 -1
3.
D) Statistically independent
4.
False
Rejection means at least one of the probabilities is not equal to the value stated in the hypothesis
