- Indifferent
- Disagree
- Strongly Disagree
Each response is assigned a numerical value, and an overall score is calculated by summing the values of all responses.

Understanding T-Distributions
True Statement: The larger the sample size, the more a t distribution resembles a normal curve.
Estimating Population Variance
When estimating the variance of a population from a sample, the sample variance cannot be used directly because it tends to be slightly too small—it underestimates the population variance.
T-Test vs. Z-Test
The difference between a t test for a single sample and a Z test for a single sample lies in how the variance of the known population

NPV Profiles: Scale Differences
A company is considering two mutually exclusive expansion plans:
Plan A
Requires a $40 million expenditure on a large-scale integrated plant that would provide expected cash flows of $6.4 million per year for 20 years.
Plan B
Requires a $12 million expenditure to build a somewhat less efficient, more labor-intensive plant with expected cash flows of $2.72 million per year for 20 years. The firm’s WACC is 10%.

1. Baker Brothers’ Days Sales Outstanding and Cash Freed Up
Question: Baker Brothers has accounts receivable of $700,000 and sales of $2,000,000. What is Baker’s days sales outstanding? How much cash would Baker Brothers free up if it reduced its days sales outstanding to 45 days?
Solution:
DSO = (Accounts Receivable / Sales) * 365
DSO = (700,000 / 2,000,000) * 365 = 128 days
Cash Freed Up = (128 days – 45 days) * (2,000,000 / 365) = $454,794.35
