QUESTION: 505

What semiannual deposit is needed to accumulate $8,000 in 5 years if the account pays 7% per year, compounded semiannually, assuming that the first deposit is made in 6 months and also assuming that the account already has $1,250 in it today?

$336.15
$677.44
$559.52
$278.01
$531.63

Answer(s): E

Explanation:

On the BAII Plus, press 10 N, 7 divide 2 = I/Y, 1250 PV, 8000 +/- FV, CPT PMT. On the HP12C, press 10 n, 7 ENTER 2 divide i, 1250 PV, 8000 CHS FV, PMT. Note that the answer this time is a positive number. This means that the $531.63 is a deposit in addition to the $1,250 original deposit. The $5,000 is entered as a negative number, because the $1,250 and the $531.63 are deposits and the $8,000 is a withdrawal. Make sure the BAII Plus has the value of P/Y set to 1.

QUESTION: 506

A variable, W, is normally distributed with a mean of 12. 68% of its observations lie between 8 and 16. The coefficient of variation of W is ________.

0.66
1.5
3.0
0.33

Answer(s): D

Explanation:

For a normal distribution, 68% of the observations lie within one standard deviation of the mean. Hence, the standard deviation of X equals 12-8 = 4. The coefficient of variation is then equal to standard deviation/mean = 4/12 = 0.33.
