Solve the Problem $\chi ^ { 2 }$ Values Can Be Approximated as Follows

question 12

Multiple Choice

Solve the problem. For large numbers of degrees of freedom, the critical $\chi ^ { 2 }$ values can be approximated as follows: $\chi ^ { 2 } = \frac { 1 } { 2 } ( z + \sqrt { 2 k - 1 } ) ^ { 2 }$ where k is the number of degrees of freedom and z is the critical value. To find the lower critical value, the negative z -value is used, to find the upper critical value, the positive z -value is used. Use this approximation to estimate the critical value of $\chi ^ { 2 }$ in a right-tailed hypothesis test with n=143 and $\alpha = 0.01$

• A) \(\chi ^ { 2 } \approx 183.411\)
• B) \(\chi ^ { 2 } \approx 189.286\)
• C) \(\chi ^ { 2 } \approx 188.134\)
• D) \(\chi ^ { 2 } \approx 184.549\)
