Answer:
See the attached for a graph.
Step-by-step explanation:
The edge of the solution space is marked by the line ...
... y = 4 - 2x
This is in slope-intercept form. It has a y-intercept of 4 and a slope of -2. Because the relation symbol is "less than" (with no "or equal to"), the line itself is not part of the solution space. It is graphed as a dashed line for that reason.
The values of y in the solution space are those <em>less than</em> the ones that make up the line, so the shading is of the half-plane <em>below</em> the line.
Answer:
We can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.
Step-by-step explanation:
Previous concepts
A statistic or sample statistic "is any quantity computed from values in a sample", for example the sample mean, sample proportion and standard deviation
A parameter is "any numerical quantity that characterizes a given population or some aspect of it".
Solution to the problem
For this case the analyst knows that from previous records that the mean for all the customers (that represent the population of interest) is
He have a random sample of n =500 customers from the previous month and he knows that 1732 represent the sample mean for the selected customers calculated from the following formula:
So on this case we can conclude that the value of 1732 is a statistic who represent the sample selected. And the value of 1622 represent the population mean from all the customers with the previous data.
