Avideo game company surveys a random sample of 250 gamers who report
annual income of $50,000. the company finds that the average gamer
spends $206 a year on games, with a standard deviation of $12.
another company is also interested in the amount game consumers spend,
and surveys a random sample of 225 gamers with a verified yearly income of
$50,000. the company finds that the average gamer spends $250 a year on
games, with a standard deviation of $15.
why is the second survey more believable than the first?
o
a. lack of randomization in the first survey
o
b. likelihood of those in the first survey to lie about the amount they
make
o
c. size of the sample for the second survey
o
d. size of the confidence interval for the second survey

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.
