Answer:

The given statement describe inferential statistics.    

Step-by-step explanation:

Descriptive Statistic:

  • It helps us to summarize a given data set.
  • It could describe the entire population or a sample from the population.
  • There are two types of descriptive measures: measures of central tendency and measures of variability
  • Central Tendency: Mean, mode, Median
  • Measure of Viability: Standard Deviation, Variance, Range, Interquartile range

Inferential Statistic:

  • It s the process of estimating population parameter with the help of a sample from the population.
  • A random sample from the population is used to describe the population with the help of sample statistic.

Given Scenario:

"Based on a sample of 170 truck drivers, there is evidence to indicate that, on average, independent truck drivers earn more than company-hired truck drivers."

Thus, this is an example of a inferential statistics as a sample was used to estimate the population.

Here,

Sample:

Sample of 170 truck drivers

Population:

All truck drivers.

With the help of a sample, we approximated the population, thus, this statement describe inferential statistics.

Slope -4 passing through the point (5,3).
bonufazy [111]
A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.

Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.

Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.

-4 as a fraction would be -4/1.

So start at (5,3), go down 4 and over 1, repeatedly and you got it.

**Just remember the rise over run can be confusing with negative slopes.**
