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?

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!

step-by-step explanation:

the answer is d

hope this

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
