Suppose a researcher obtains a negative number for the calculated value in a Chisquare test. What can you conclude because the value is negative? A. The observed frequencies are much smaller than the expected frequencies B. The expected frequencies are much smaller than the observed frequencies C. The researcher made a mistake because the calculated value of Chi-square cannot be negative D. There are very large differences between the observed frequencies and the expected frequencies
Suppose a researcher obtains a negative number for the calculated value in a Chisquare test. What can you conclude because the value is negative?
A. The observed frequencies are much smaller than the expected frequencies
B. The expected frequencies are much smaller than the observed frequencies
C. The researcher made a mistake because the calculated value of Chi-square
cannot be negative
D. There are very large differences between the observed frequencies
and the expected frequencies
5. Suppose a researcher is using a one-way Chi-square test to determine whether people have a significant preference among three fast-food restaurants. The null hypothesis would state that:
A. there is a real preference in the sample
B. one-third of the population prefers each restaurant
C. one-third of the sample prefers each restaurant
D. one restaurant is preferred over the others in the population
6. Suppose a researcher asks 600 participants to state their preference among 3 flavors of ice cream. In this study, the expected frequency (E) value would be:
A. 100
B. 150
C. 200
D. 160
