Question 13
The personnel department of a large corporation gives
two aptitude tests to job applicants. One measure verbal
ability; the other, quantitative ability. From many
years' experience, the company has found that the verbal
scores (V) tend to be normally distributed with a mean of 45
and a standard deviation of 8. The quantitative scores
are normally distributed with a mean of 85 and a standard
deviation of 10, and they appear to be independent of the
verbal scores. A composite score, C, is assigned to each
applicant, where C=2V+3Q. If a company policy prohibits
hiring anyone whose C score is below 380, what percentage
of applicants will be rejected?
A 25%
93%
85%
D 75%

In a newspaper ad, a car dealer lists a 2001 Chrysler,
a 2010 Ford, and a 2008 Buik. If the number of inquiries
he will get a bout these cars may be regarded as independent
random variables having Poisson distributions with the
parameters A₁ = 3.1, A₂=2.6, A3 = 5.3. What is the
probability that altogether he will recieve fewer than 7
inquiries about these cars?
