1 Use the appropriate table to find the following chisquare

1) Use the appropriate table to find the following chi-square value x2.05 for df = 3

a) 0.352 b) 7.815 C) 9.488 D 5.991

2) Use the appropriate table to find the following probability: P(x2 < 13.277) for df = 4

a) .990 b) .005 c) .995 d) .010

Solution

1. Using a table,

chi^2 = 0.352 [ANSWER, A]

*******************

2. Using a table,

P(chi^2 < 13.277) = 0.990 [ANSWER, A]
