Q3)

A hypothesis-testing procedure that examines how well an observed frequency distribution of a single nominal variable fits some expected pattern of frequencies is a(n):

1) chi-square test for independence

2) chi-square for goodness of fit

3) observed frequency test

4) multiple correlation

Q4)

In a chi-square test for goodness of fit, the null hypothesis is that:

1)the number of people in one category is no greater than the number of people in the other

2) the variances of the populations of categories are the same

3) the proportion of people over categories breaks down the same for the two populations

4) the means of the two populations of categories are the same

Q5)

The __________ distribution is always greater than 0 and skewed to the right (most scores clumped on the left, with a tail on the right).

1) Z

2) t

3) ?2

4) F
