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 $45,000 per year, and the marketing student has an
offer for $43,000 per year. Summary information about the distribution of salary offers for each major follows:
Accounting:mean = $46,000 standard deviation = $1,300
Marketing:
mean = $42,500 standard deviation = $900
For problems A and B calculate the appropriate z scores rounded to one decimal place.

O Because the means are different.
O Because one of the values is greater than the mean and the other is less than the mean.
O Because the values being compared are different.
O Because the standard deviations are different.
