Answer the following....

A) How are expected frequencies computed for goodness-of-fit tests? 1. Divide the proportion of the sample size for each category by the total sample size. 2. Divide the total sample size by the sample size for each category. 3. Take the proportion of the sample size for each category from the observed data. 4. Take the proportion of the sample size for each category designated by the proposed distribution.

B) When the sample evidence is sufficient to justify rejecting the null hypothesis in a goodness-of-fit test, can you tell exactly how the distribution of observed values over the specified categories differs from the expected distribution?Choose one 1. No. When we reject the null, we can tell exactly how the observed distribution is different from the expected distribution. 2. No. When we reject the null, we can only conclude that the observed distribution is different from the expected distribution. 3. Yes. When we reject the null, we can tell exactly how the observed distribution is different from the expected distribution. 4. Yes. When we reject the null, we can only conclude that the observed distribution is different from the expected distribution.

C) For a chi-square goodness-of-fit test, how are the degrees of freedom computed? 1. The number of categories plus one. 2. The number of categories minus three. 3. The number of categories minus two. 4. The number of categories minus one.
