Operation Research Grade Statistics Grade A B C Other A 25 6 17 13 B 17 16 15 6 C 18 4 18 10 Other 10 8 11 20 Are the grades in statistics and operations research related? Use α = 0.01 in reaching your conclusion. What is the P-value for this test?

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
