Answer: An interval is a range of values for a statistic.
Explanation:
For example, you might think that the mean of a data set falls somewhere between 10 and 100 (10 < μ < 100). That “somewhere between 5 and 15%” is an interval estimate.
Answer:
Explanation:
All but kg can be vector quantities.
m/s^2 is acceleration. in the formula F = m*a the acceleration has direction and that means that force has direction. If you place an object on a table, there are 2 vectors in operation: one tends to move down (gravity) and one points up (the table top). The object would like to move but cannot, because the forces are equal but in opposite directions.
meters can be a vector or the unit of a vector. It is called displacement when it has direction.
km / hr. Since meters can be a vector, so can km. This is a velocity (or can be). When the direction is not specified, km/hr is a speed. It might describe the movement of a snail. hours really have no direction. hours can't go up, or down or left or right, the way km can. So hours add nothing to the question.
kg are units of mass. Mass really has no direction associated with it. Don't confuse mass and weight. Weight does have a direction, but mass does not.
The code chunk that lets the analyst create the phone_number column is: unite(customers, "phone_number", area_code, phone_num, sep="-"
<h3>What is a data frame?</h3>
A data frame refers to a two-dimensional array-like structure or table that is made up of rows and columns, which is typically used for storing data in R Studio using the R programming language.
In Computer programming, a data frame is a list of vectors that are all equal in length, and each column consist of values of one variable while each row consist of a set of values from each column.
<h3>The executable code in R Studio.</h3>
In this scenario, the code chunk that would be used to create a data frame that combines the two columns into a single column (phone_number) is:
- unite(customers, "phone_number", area_code, phone_num, sep="-"
