I am working on a statistical test problem. I have been given salaries for 2017 and 2018 years for Los Angeles County, approximately 10,000 records in 2017 and 9,000 records in 2018. I am trying to assess whether there was an increase in salaries between the years. My Lternative hypothesis is the records greater than 2016, and my null hypothesis is any records equal to or less than 2017.
How do I calculate the data?

I DONT KNOW THAT

Step-by-step explanation:

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

1/3 + 1/5 = 8/15.
