An example of a study that has a false correlation caused by a lurking variable is " research scientist examines the influence of diet and exercise on a an individual's blood pressure."
<h3>What is a lurking variable in a study?</h3>
Lurking variable is known to be a kind of a variable that is said not be the explanatory variable nor can it be called the response variable but it is one that is seen to have a relationship (e.g. correlation) with the response and that of the explanatory variable.
Note that A lurking variable is one that can be falsely identify as a strong relationship that exist between variables or it is one that often hide the true relationship.
Hence, An example of a study that has a false correlation caused by a lurking variable is " research scientist examines the influence of diet and exercise on a an individual's blood pressure."

The following is part of the computer output from a regression of monthly returns on Waterworks stock against the S&P 500 index. A hedge fund manager believes that Waterworks is underpriced, with an alpha of 2% over the coming month.
Beta = 0.75
R-square = 0.65
Standard Deviation of Residuals = 0.06 (i.e., 6% monthly)
Assuming that monthly returns are approximately normally distributed, what is theprobability that this market-neutral strategy will lose money over the next month?
Assume the risk-free rate is .5% per month.
Answer:
0.33853
Explanation:
Given that, the expected rate of return of the market-neutral position is equal to the risk-free rate plus the alpha:
0.5%+ 2.0% = 2.5%
Hence, since we assume that monthly returns are approximately normally distributed.
The z-value for a rate of return of zero is
−2.5%/6.0% = −0.4167
Therefore, the probability of a negative return is N(−0.4167) = 0.33853
Answer:
D. $525,000
Explanation:
budgeted production = 15,000 units/month
unit production time required = 30 minutes => 0.5 hours
direct labor rate = $70 per hour
Budgeted cost of direct labor for the month = 15,000 * 0.5 * 70
= $525,000
