(f) The area under the z curve between −1 and 1 .6826 Correct: Your answer is correct. (g) The area under the z curve between −5 and 5 .3830 Incorrect: Your answer is incorrect.

Answer 1

Answer:

  (g) The area under the z curve between −5 and 5 is 1.0000

Step-by-step explanation:

The area between z=-5 and z=5 is about 0.9999994267. Rounded to 4 decimal places, it is 1.000.

___

The incorrect answer shown in your problem statement is the approximate area between -0.5 and +0.5. My calculator says that area is 0.3829--but that is not what the question asked.
