2. Find the value of x2 for 12 degrees of freedom and an area of .025 in the right tail of the chi-
square distribution curve. What is the value of chi-square? Round to three decimal places
3. Determine the value of x2 for 14 degrees of freedom and an area of .10 in the left tail of the
chi-square distribution curve. What is the value of chi-square? Round to three decimal places
4. Determine the value of x2 for 23 degrees of freedom and an area of .990 in the left tail of the
chi-square distribution curve. What is the value of chi-square? Round to three decimal places.
5. Α ____________ compares the observed frequencies from a multinomial experiment with
expected frequencies derived from a certain pattern or theoretical distribution. The test
evaluates how well the observed frequencies fit the expected frequencies.
A. Goodness-of-fit test
B. Chi-square test
C. Linear regression
6. The __________ are the frequencies obtained from the performance of a
multinomial experiment. The expected frequencies are the frequencies that we expect to obtain
if the null hypothesis is true.
A. Observed frequencies
B. Expected frequencies
C. Fluctuating frequencies
