Which of the following analyses involves making hypothetical changes to the data associated with a problem and observing how these changes influence the results? Select one: a. predictive analysis b. linear regression analysis c. what-if analysis d. multivariate analysis e. time-series analysis

The correct answer is letter "C": what-if analysis.

Explanation:

A what-if analysis is a study an individual or company makes about a certain number of events where variables are changed to determine what the outputs would be. This approach is normally implemented when there is limited information from where to make a concise decision. Then, individuals have to outline all the possible results to find out what their risks are.

Software like Microsoft Office Excel facilitates the implementation of what-if analysis.

He estimated that he had about $9 worth of groceries

Step-by-step explanation:

Given that

Gallon of milk =  $3.49

Three pounds of  oranges = $1.14(3) = $3.42

Box of cereal =  $3.46

Here the front end estimation should be applied that means only considered the number that shows in the front side and the remaining numbers should be zeros

Now applying the front end estimation, It shows like this

$3.49 => $3.00

$3.42 => $3.00

$3.46 => $3.00

Now sum of all 3 that comes 9

Therefore the second option is correct
