A program evaluator wanted to know if a combination of experience and education gave leadership candidates an advantage in meeting job performance standards better than experience alone, or education alone. There were a total of 39 candidates who had both experience and education, and 200 candidates who had either experience or education. Of the candidates who had both experience and education, 21 met the standards, while 18 did not meet the standards. Of the candidates who had only experience or education, 100 met the standards, and 100 did not meet the standards. Select the correct statistical test to determine if there is a relationship between preparation and meeting the standards, calculate the results, and communicate the results.

a. None of the choices are correct.
b. A chi-square test would be the best choice for examining observed data. The results are significant, (X 2 [ 1, N = 239] = 0.19, p < .05). This means that there was a relationship between preparation and meeting the standards, we reject the null hypothesis that the variables are independent.
c. A chi-square test would be the best choice for examining observed data. The results are not significant (X 2 [ 1, N = 239] = 0.19, p> .05). This means that there was not a relationship between preparation and meeting the standards, we retain the null hypothesis that the variables are independent.
d. A Spearman's rs is the best choice. The test reveals that there is a strong correlation between preparation and meeting the standards (rs = [237] = 1.00, p < .05). This means there is a relationship between the variables.

Asmall (but heavy) particle placed in a glass of water will follow a zigzag motion because the particle will bounce off of the water molecules it meets. this is called brownian motion. a physicist simulates this on a computer, by varying the distance a particle can travel (called the mean free length), on average, before it collides with a water molecule and assigning the change in motion to be one of 8 directions, each with a similar probability. by running the simulated particle (with the same mean free length) many times she determines that it should take 15 seconds, on average, for the particle to fall to the bottom, with a standard deviation of 1.5 seconds. next she lets a real particle fall through a glass of water and finds that it took 18 seconds. what does she conclude, and why?
