If a distribution has a mean of 30 and a standard deviation of 5,how many standard deviations is 60 from the mean?

A) 5
B) 6
C) -6
D) 0

To find how many standard deviations 60 is from the mean, we use the formula z = (x - μ) / σ, where z is the number of standard deviations from the mean, x is the value we're interested in (in this case, x = 60), μ is the mean, and σ is the standard deviation. Plugging in the values given, we get z = (60 - 30) / 5 = 6. Therefore, 60 is 6 standard deviations from the mean. The answer is B.
