A distribution has a mean equal to 12 and a standard deviation of 36. It has a coefficient of variation equal to:

  1. zero
  2. none of these answers
  3. 0.335
  4. 3.00

Answer(s): D

Explanation:

The coefficient of variation equals the standard deviation divided by mean.



John's great-grandfather left him $100 when he died 100 years ago in an account paying 5% per year, compounded annually. How much would the account hold for John now?

  1. $12,504.51
  2. $13,150.13
  3. $14,229.78
  4. $8,407.76
  5. $14,113.90

Answer(s): B

Explanation:

On the BAII Plus, press 100 N, 5 I/Y, 100 PV, 0 PMT, CPT FV. On the HP12C, press 100 n, 5 i, 100 PV, 0 PMT, FV. Note that the answer will be displayed as a negative number. Make sure the BAII Plus has the P/Y value set to 1.



If we reject the null hypothesis what can we conclude subject to the alpha risk?

  1. Alternative hypothesis is false
  2. Null hypothesis is false
  3. Null hypothesis is true
  4. Both the null hypothesis and the alternative hypothesis are false
  5. Both the null hypothesis and the alternative hypothesis are true

Answer(s): B

Explanation:

The alpha risk is the probability of rejecting the null when it is actually true. So if we had rejected the null, we can conclude, given what we know of the alpha, that the null is false.



Which is true of all skewed distributions?

  1. They are is not symmetrical.
    II. Their mean and median are not equal.
    III. They are characterized by many small values and a few extreme values.
  2. I and III
  3. None of these answers is correct.
  4. I and II
  5. II and III

Answer(s): C

Explanation:

A skewed distribution is not symmetrical and its mean and median are not equal. While a positively skewed distribution is characterized by many small values and a few extreme values, the opposite is true of negatively skewed distributions. So III is false as far as "all skewed distributions" are concerned.
