A used car dealer says that the mean price of a​ three-year-old sports utility vehicle is ​$22,000. You suspect this claim is incorrect and find that a random sample of 25 similar vehicles has a mean price of ​$22,549 and a standard deviation of ​$1995. Is there enough evidence to reject the claim at α=0.05​?

what are the answear choices to the question.

step-by-step explanation:

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)
