To find how many standard deviations 600 is from the mean, we need to calculate the z-score:
z = (x - μ) / σ
where x is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation.
Plugging in the values, we get:
z = (600 - 1000) / 100 = -4
This means that 600 is 4 standard deviations below the mean. Therefore, the best answer choice is B, which corresponds to -4.
