You can put this solution on YOUR website! The reading speed of 2nd grade students in a large city is approximately normal, with a mean of 89 words per minute and a standard deviation of 10 words per minute.
what is the probability a randomly selected student in the city will read more than 93 words per minute?
--------
z(93) = (93-89)/10 = 0.4
-------
P(x > 93) = P(z > 0.4) = 0.3446
