Applications of Normal Distribution in Daily Life: Real-World Examples | A Level Mathematics

Here we are discussing the following problem
A company manufactures light bulbs, and the lifespan of these bulbs follows a normal distribution with a mean of 1200 hours and a standard deviation of 150 hours. If the company wants to guarantee that 90% of the light bulbs will last at least a certain number of hours, what should this minimum guaranteed lifespan be?

The Normal Distribution in Everyday Scenarios: Understanding the Bell Curve This topic explores how the normal distribution, commonly known as the bell curve, appears in various everyday scenarios. By understanding the properties of the bell curve, we can gain insights into patterns and trends in our daily lives, from the distribution of heights in a population to the variation in test scores among students.
