# critical value

For a one-tailed left z test with alpha=0.07, what is the critical value?

a. -1.81
b. -1.47
c. 1.48
d. -1.48

(b) -1.48 Subtract the alpha value from one. The alpha value is expressed as decimal less than one. In this example the alpha value is .07: 1.0 -.07 =.93 Look in the "z" table for .93. If the number itself is not present, then choose the closest match. .93 is displayed. Find the corresponding number...
