Solve the problem. For large numbers of degrees of​ freedom, the critical chi χ squared 2 values can be approximated using the f

ormula chi χ squared 2 equals = one half (x plus StartRoot 2 x minus 1 EndRoot )squared 1 2 z+ 2k−12​, 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 χ squared 2 in a​ right-tailed hypothesis test with n equals =143 and alpha α equals =0.01.

Answer:

1. x = -7

2. x = 6/13

3. x = 7/12

Step-by-step explanation:

1. x = 21 / -3

x = -7

2. 13x = 6

x = 6 / 13

x = 6/13

3. -12x = -7

x = -7 / -12

x = 7/12
