Slandard 6. Circle the correct Statements Use the 68-95-99.7 (i.e. Empirical) rule to answer both parts of this the best response for each part and circle your answer(s) clearly. (A) Circle one. A 100 poi int exam was given. John's score on the exam was at the 16th percentile. All scores for the exam were normally distributed with mean of 67 and standard devi What was John's exam score, according to the calculations based on the Empirical rule? i. 55. ii. 67, iv. 7 one of the above.

What proportion of students scored worse than Eric? i. 0.6800. i. 0.9985. i., 0.0500. 0.0015. v. 0.9735. vi. None of the above. in re TRUE (T) statements and which onExplanation / Answer
(A) = 67, = 4
Area under the standard normal curve is 0.16 to the left of z = -0.9945
John's score = + z * = 67 - 0.9945 * 4 = 63
(v) None of the above
(B) z = (x - )/ = (55 - 67)/4 = -3
Area under the standard normal curve to the left of z = -3 is 0.0013
(iv) 0.0015
