1. Suppose that two graduating seniors, one a marketing major and one an accounting major, are comparing job offers. The accounting major has an offer for $55,000 per year, and the marketing student has an offer for $53,000 per year. Summary information about the distribution of offers is given below.






















Accounting:mean =56,000    standard deviation =1,200
Marketing:mean =52,500    standard deviation =800



Then calculate the appropriatez scores. (Round your answers to two decimal places.)


accounting z score =









55,000 − 56,000
1,200

=


(so $55,000 is  standard deviations below the mean)


marketing z score =









53,000 − 52,500
800

=


Relative to the appropriate data sets, the marketing offer is actually more attractive than the accounting offer (although this may not offer much solace to the marketing major).

Why is one of thez scores positive and the other one negative?


Because the means are different.

Because the standard deviations are different.

Because one of the values is greater than the mean and the other is less than the mean.

Because the values being compared are different.
