I am going to take the BEC section this coming July. Right now, I am practicing AICPA released questions posted on Becker’s Web site. I started with 2007 questions and now doing 2012 questions. While I appreciate Becker’s efforts to publish answers with explanations (but not for 2012 questions because of timing), I have felt some of Becker’s explanations are not correct. I found one of this kind for REG among the past year released questions (I forgot which year but this was regarding the corporate basis) and especially this tendency is more dominant with BEC.
In 2012 release questions, the first question goes as,
The coefficient of determination, r squared, in a multiple regression equation is the:
a. Percentage of variation in the independent variables explained by the variation in the dependent
b. Percentage of variation in the dependent variable explained by the variation in the independent
c. Measure of the proximity of actual data points to the estimated data points.
d. Coefficient of the independent variable divided by the standard error of regression coefficient.
Choice “b” is correct.
But I believe the correct answer is “c” because the question is asking about “coefficient of determination” Since the coefficient of determination is expressed as 1- (Sum of squared difference between actual and predicted vales derived from the binominal equation) / (squared sum of actual values), this is the goodness of fit. But it seems Becker confused the coefficient of determination with the coefficient of correlation. I need to know if I am wrong.
I am studying with only Wiley and passed REG for 91 in May 2012. For REG, Wiley is especially hard to read because of the layout and ways of explanations (The tend to explain the simple things in a way difficult to understand and similar concepts are scattered all over the different pages), but they do not have such fundamental mistakes as above (except within manageable numbers of typos).
How did u figure out question # 29 on the AICPA 2012 released questions:.. doesnt seem complicated but not getting the right answer for some reason 🙁 dont know what im doing wrong
ceramics manufacturer sold cups last year for $7.50 each. Variable costs of manufacturing were $2.25
per unit. The company needed to sell 20,000 cups to break even. Net income was $5,040. This year,
the company expects the following changes: sales price per cup to be $9.00; variable manufacturing
costs to increase 33.3%; fixed costs to increase 10%; and the income tax rate to remain at 40%. Sales in
the coming year are expected to exceed last year’s sales by 1,000 units. How many units does the
company expect to sell this year?
how is the answer d.. i got C
((7.50 – 2.25) * 20,000)*=105,000
Before-tax income: 5,040/0.60 = 8,400
This year sold units: (105,000+8,400)/(7.50 – 2.25) = 21,600
Company expect to increase sale of units by 1,000, so 21,600+1,000 = 22,600
