Probability light bulb pdf
WebbA light bulb is burned until it burns out. The random variable Y is its lifetime in hours. Y can take any positive real value, so Y is a continuous random variable. Examples of continuous random variables include height, weight, the amount of sugar in an orange, the time required to run a mile. Probability Mass Function: Webb29 apr. 2024 · The sampled bulbs last an average of 260 days, with a standard deviation of 90 days. If the CEO's claim were true, what is the probability that 18 randomly selected bulbs would have an average life of no more than 260 days.
