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."

Answer and Explanation:
The computation is shown below:
a. Holding period return would be
= Income + (End of Period Value - Initial Value) ÷ Initial Value
= 0 +($2,178 - $1,902) ÷ $1,902
= 0 + $276 ÷ $1,902
= 14.51%
b. The annual percentage rate is
For 3 months, the rate is 14.51%
Now
For 12 months, it is
= 14.51% ÷ 3 × 12
= 14.51 % × 4
= 58.04%
c. The effective annual rate is
= ( 1 + r ÷ m)^m - 1
= (1 + 58.04% ÷ 4)^4 - 1
= (1 + 0.5804 ÷ 4)^4 - 1
= (1 + 0.1451)^4 - 1
= (1.1451)^4 - 1
= 1.719387079 - 1
= 0.719387079 or 71.94%
Answer:
Initial outlay = $250,000
Annual cash inflow = 25% x $250,000 = $62,500 per annum
Payback period = <u>Initial outlay</u>
Annual cash inflow
= <u>$250,000</u>
$62,500
= 4 years
Explanation:
In this respect, there is need to calculate the annual cash inflow, which is 25% of initial outlay. Then, we will divide the initial outlay by the annual cashflow. This gives the payback period of the machine.
The answer to the question is that the substitution of domestic steel for foreign steel absorbs resources that would otherwise produce goods of great value.
Though America is declining in terms of domestic steel production, it does not mean the nation as a whole is failing, including in terms of production. Since the skills that workers use to produce steel are transferable to other industries, this allows them to be involved in industries that are creating more relevant value right now than steel; choosing to return to domestic steel production might prove to be inefficient.
