Suppose the temperature of a cup of coffee is normally distributed with a mean of 142 degress F. If a cup of coffee has a z score of 1.5, which of the following is true?

None of the above.
You cannot copy and paste here. Also, if you don't know the standard deviation, you cannot determine the temperature in that cup.
Z = (score-mean)/SD
Z = (score-mean)/SD
