Question

Find the critical values X2L and X2R that correspond to the given confidence level and sample size: 99%; n = 28 This involves using chi-square, critical vaules and area.  

Answer 1

3734057 We need to find the chi-square critical values ( 99% confidence level and 28 sample size ,-28,α-0.01 Then, the degrees of freedom, df-n-1 and ) that correspond to =28-1 27 For a two tailed test, find the lower critical value, 0.01 find | |-- = The critical value at 27df corresponding to 0.995 upper tail area is 11.808 That is, 11.808 = 0.995 For a two tailed test, find the lower critical value, find -(0.01 The critical value at 27df corresponding to 0.005 upper tail area is 49.645 That is, -49.645 40685 = 1-1 = 0,005
