Aliun [14]

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.

What is the vertex of the parabola whose equation is y = (x + 1)^2 + 3?
dalvyx [7]
The y-value of the vertex is positive 3, as shown by the +3 on the right hand side of the equation, and the x-value is -1, from the (x+1)^2 (remember, when the number is inside the brackets, flip the sign) The vertex would be (-1, 3) 

If you are looking for a rigorous answer (calculus), we must find the mininum point of the equation: f(x) = (x+1)^2 + 3 f
f'(x) = 2(x+1) = 2x + 2
2x + 2 = 0 
x = -1
f(1) = (-1 + 1)^2 + 3
f(1) = 0 + 3 = 3
(-1, 3)
