“The heights of students at a high school are normally distributed with a mean of 165 cm and a standard deviation of 10 cm. What is the probability that a randomly selected student is taller than 180 cm? The test scores on a standardized exam are normally distributed with a mean of 500 and a standard deviation of 100. What percentage of students scored between 450 and 600? The lifespan of a certain brand of lightbulb is normally distributed with a mean of 1200 hours and a standard deviation of 75 hours. What is the probability that a randomly selected lightbulb will last less than 1050 hours?”
