The percent confidence interval is the range having the percent probability of containing the actual population parameter. Question 4. The Chi Square test can be performed on categorical (nominal) level data. Question 5. For a one sample confidence interval, the interval is calculated around the estimated population or standard. Question 6. The chi square test is very sensitive to small differences in frequency distributions. Question 7. The probability that the actual population mean will be outside of a 98% confidence interval is Question 8.

A contingency table is a multiple row and multiple column table showing counts in each cell.
