For each of the Z-scores below, determine two probabilities (show four three decimal places): (1) the probability above the Z-score and (2) the probability below the Z-score (8 points)
2.40: Probability above: __________________________
Probability below: __________________________
-0.48: Probability above: __________________________
Probability below: __________________________
Homework Answers
solution
(A)P(z >2.40 ) =1 - P(z <2.40 )
Using z table,
= 1 -0.9918
probability= 0.0082
(B) P(z <-0.48) =0.3156
probability=0.3156

This Question: 1 pt was 57. The tost scores of four students selected at random are 15, 22, 8, and 37. A standardized exam's scores are normaly distributed. In a recent year, the mean lost score was 20.9 and Find the scores that correspond to each value and determine whether any of the values are unusual The 2-score for 150 (Round to two decimal places as needed) The score for 22 is (Round to two decimal places as needed.)

Use the random decimal fraction generator at Random.org, linked here, to generate a list of three fractions with four decimal places. Assume those decimal fractions represent probability values associated with z-scores. Then use the standard normal table to look up the z-score that is closest to matching with that probability. List them below. (3 points) probability value (generated fraction) = associated z-score = probability value (generated fraction) = associated z-score = probability value (generated fraction) = associated z-score = The...
