Suppose that your statistics professor tells you that the scores on a midterm exam were approximately
DedPeter [7]

Answer:

  • Yes

Step-by-step explanation:

z-score representing 85% is 1.04 (from table)

Let x be the score representing the lower limit of 85%.

<u>Use the formula to find z-scores:</u>

  • z = (x - μ)/σ

<u>We have:</u>

  • z = 1.04, μ = 78, σ = 7

<u>Substitute the values and solve for x:</u>

  • 1.04 = (x - 78)/7
  • x - 78 = 7.28
  • x = 85.28

The lower limit of the top 15% is 85.28.

Since your score is greater than 85.28 you earned an A
