Which of the following statements are not true?
A) The chi-squared distribution is used to obtain a confidence interval for the variance $\sigma ^ {2 }$
Of a normal population.
B) Provided that $n p _ { i } \geq 5$
For every i (i =1, 2,……, k), the $\chi ^ { 2 }$
Goodness-of-fit test statistic when all k category probabilities are completely specified has approximately a t distribution with k-1 degrees of freedom.
C) A multinomial experiment generalizes a binomial experiment by allowing each trial to result in one of k possible outcomes, where k2. In general, we refer to these outcomes as categories.
D) All of the above statements are correct.
E) None of the above statements are correct.

D) All of the above statements are correct.
E) None of the above statements are correct.

Quizplus · Accepted Answer

Statement B is incorrect because the $\chi^{2}$ goodness-of-fit test statistic, under the condition that $n p_{i} \geq 5$ for every i, follows approximately a $\chi^{2}$ distribution with $k-1$ degrees of freedom, not a t distribution.
