Discussion about a chi-square curve


Solve the following:

Q1: The t-table has entries for areas of 0.10,0.05,0.025,0.01, L0.005. In contrast, the x2-table has entries for those ar¬eas and for 0.995, 0.99, 0.975, 0.95, and 0.90. Explain why the t-values corresponding to these additional areas can be obtained from the existing f-table, but must be provided explicitly in the x2-table.

Q2:  For a Chi-square curve with 22 d.f., find the Xz-value that has area

a. 0.01 to its right. b. 0.995 to its right.

Q3:  For a x -curve with df = 4, determine car Sales. The American Automobile Manufacturee ssociation compiles data on U.S. car sales by type of eai. Following is the 1990 distribution, as reported in the World Almanac.
