Bumek [7]

Are you familiar with z-scores? According to the definition,

(given numerical value) - (mean)
z = ---------------------------------------------
standard deviation

Thus, with the given numerical value equal to 410 and the std. dev. equal to 75, the corresponding z-score is

410-500 -90
z = --------------------- = --------------- = -1.2
75 75

Use a table of z-scores to determine the area under the standard normal curve to the left of z = -1.2. Your result is the probability that a given family chosen at random spends less than $410 per month.
