You want to know if there's an association between college students' spring break
destinations and what year they're in. You take a random sample of 405 college
students and record the following data:
A. Set up your null and alternative hypotheses.
B. What are your degrees of freedom?
C. Using your TI­83, compute the expected values for each cell.
D. Will a chi­square hypothesis test of independence be valid in this situation?
Explain.
E. What are your test statistic (X^2 ) and P­value?
F. What can you conclude if a = .01?

d 600 because 15*10*2=300

300+300=600

step-by-step explanation:

the real question is why is this guys last name heavyfoot

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
