Please answer step by step, applying normal distribution
formulas, the previous answer you provided me was incomplete. I
need calculations and formulas:
The Rivera family has twin girls, Rosa and Maria. They both
graduated from college two years ago and now each earn $50,000 a
year. Maria works in the retail industry, where the mean salary for
executives with less than five years of experience is $35,000, with
a standard deviation of $8,000. Rose is an engineer. The mean
salary for engineers with less than five years of experience is
$60,000, with a standard deviation of $5,000. Compute the Z-scores
for Rosa and Maria, and comment on the results.
