Topic: ChiSquare 10. In a contingency table, if all of the expected frequencies equal the observed frequencies,
then we can conclude that there is a perfect association between rows and columns.

Topic: ChiSquare 11077 Chapter 01  An Introduction to Business Statistics 11. When using chisquare goodness of fit test with multinomial probabilities, the rejection of
the null hypothesis indicates that at least one of the multinomial probabilities is not equal to
the value stated in the null hypothesis.

Topic: ChiSquare 12. A fastener manufacturing company uses a chisquare goodness of fit test to determine if a
population of all lengths of ¼ inch bolts it manufactures is distributed according to a normal
distribution. If we reject the null hypothesis, it is reasonable to assume that the population
distribution is at least approximately normally distributed.

Topic: ChiSquare 13. When using the chisquare goodness of fit test, if the value of the chisquare statistic is
large enough, we reject the null hypothesis.

Topic: ChiSquare 11078 Chapter 01  An Introduction to Business Statistics 14. The chisquare goodness of fit test can only be used to test whether a population has
specified multinomial probabilities or to test if a sample has been selected from a normally
distributed population. It cannot be applied to test if a sample data comes from other
distribution forms such as Poisson.

Topic: ChiSquare 15. In performing a chisquare test of independence, as the difference between the respective
observed and expected frequencies decrease, the probability of concluding that the row
variable is independent of the column variable decreases.

Learning Objective: 3
Topic: ChiSquare 16. In performing a chisquare goodness of fit test with multinomial probabilities, the smaller
the difference between observed and expected frequencies, the higher the probability of
concluding that the probabilities specified in the null hypothesis is correct.

Topic: ChiSquare 11079 Chapter 01  An Introduction to Business Statistics 17. When we carry out a chisquare test of independence, if ri is row total for row i and cj is
the column total for column j, then the estimated expected cell frequency corresponding to
row i and column j equals (ri) (cj)/n.

Topic: ChiSquare 18. When we carry out a chisquare test of independence, the chisquare statistic is based on
(rc1) degrees of freedom where r and c denote, respectively the number of rows and columns
n the contingency table.

state that the two classifications are statistically independent.
