Study Session 2: Quantitative Methods: Basic Concepts

TVM problem with calculator

When it should be: N = 2; I/Y = 10; PV = –200; CPT → FV = $242 my calculator shows FV=231,5

Whats is wrong?

Decision Trees - Std Deviation with BA II PLUS

How can I calculate this through BA II Plus? I know how to do this in steps but it takes too much time.  I am calculating the Expected Value, then the Variance and then the Std Dev through the square root.

Exercise is:

The probability distribution for a company’s sales is:

Probability
Sales ($ millions)

0.05
70

0.70
40

0.25
25

Q. The standard deviation of sales is closest to:

1. 9.82 million

2. 12.20 million

TVM Sign Convention

Hello guys

Using Kaplan 2018. In the example just before the “FV of Annuity Due” there’s a Note:

TVM Problem - Issue with the Wording

I came across this easy question that’s messing with me based on the wording of one part of it. Any helpers?

“A client can choose between receiving 10 annual $100,000 retirement payments, starting one year from today, or receiving a lump sum today. Knowing that he can invest at a rate of 5 percent annually, he has decided to take the lump sum. What lump sum today will be equivalent to the future annual payments? “

I highlighted that last bit because that’s the part that’s tripping me up. I know that the way to solve this with the calculator would be:

Quant Probability Concepts Question

Two boxes contain chips of different colors. Whereas the first box has 45 red chips
and 55 blue chips, the second box contains 70 red chips and 30 blue chips. You pick
one chip from either of the boxes and it turns out to be blue. Given the facts above,
what is the probability that the blue chip you picked came from the second box
assuming that both boxes have the same probability of being chosen

Could someone help me with this question. I’m terrible at probability, just having a hard time in general understanding the concepts.

Quant Statistical Concepts & Mkt Returns problem

An investor is using a screening program to select stocks. The first criterion is to limit
further analysis to the top quintile of companies with return on assets (ROA).
Ranking a database of 1,200 firms from lowest to highest ROA produced an array,
which is excerpted in the following table.

Rank
ROA
Rank
ROA

958
9.00%
962
10.30%

959
9.20%
963
10.60%

960
9.90%
964
10.70%

TVM Question

A company’s annual sales figures over the last four years are as follows: $2.6 million;
$3.1 million, $5.3 million, $7.0 million. The firm’s compound annual growth rate over
the period is closest to

28%

39%

56%

The solution uses 3 years to calculate the growth rate and hence the answer is 39%

I’m not understanding why itsn’t 4 years. Could someone kindly explain this to me.

Quant TVM problem

An investor is evaluating an insurance product that promises to pay a $1,000
monthly benefit for 20 years beginning 10 years from now. The investor is required
to make payments at the end of each month for the next five years. Assuming a five
percent discount rate and monthly compounding, the minimum monthly payment
required to finance the benefit is closest to:

$1,743

$1,912

$2,228

Could someone tell me their method of solving?
