B) Anticipatory Grief
Explanation:
As Khalid has found out that his friend Jason is terminally ill. This has made him feel sad and lonely at the thought of living life without his friend. Khalid's feelings best represent the concept of anticipatory grief which refers to the feeling of sadness and grief occurring before the actual happening of that loss. We become sad and emotional even before the actual happening of some incident.

The total percentage return on the investment is:
= -7.86%.
Explanation:
a) Data and Calculations:
Initial share price at which the stock was purchased = $140
The selling share price = $119
Dividends earned during the stock ownership (holding period) = $10
Total returns, including proceeds from the sales = $129 ($119 + $10)
Total returns from holding the stock until sold
= Total returns + sales proceeds minus Initial purchase cost
= -$11 ($129 - $140)
Total percentage return on the investment = $11/$140 * 100
= 7.857
= 7.86%

Answer : The p-value of 0.0743 is greater than alpha at 0.05; so we fail to reject the null hypothesis and conclude that there is no significant difference in the number of unique users before and after a change in policy.
In this question, the manager wants to know if the number of users has changed.
So, the null and alternate hypotheses are:
Null Hypothesis: 
Alternate Hypothesis : 
Type of test : Two-tailed test
The level of significance is 95%
We can calculate alpha (α) as follows:
The p value = 0.0743.
We use the following rules to arrive at a conclusion when p-values and alpha is given:
If 
, reject the null hypothesis
If 
, we don't reject the null hypothesis.
Since the p-value is greater than alpha, we don't reject the null hypothesis.
Answer:
E. efficiency wages
Explanation:
Clearly this isn't a discrimination case, as Rob has a robust background with the company (15 years). Although their work output may be the same, Rob's experience justifies the higher pay.
This is one form of efficiency wage theory, holding that higher wages lead to increased employee productivity. This way, Rob gets an incentive for staying with the company.
