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:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
