WILL GIVE BRAINLIEST The lifespan of a laptop battery is normally distributed. If the mean lifespan of a battery is 4 years with a standard deviation of 1.6 years, what is the probability that the next laptop battery you purchase will last between 3.5 and 5.5 years? 84.79% 15.2196 55.19% 44.81%
First determine the z-scores for 3.5 and 5.5 years. After matching the z-scores with the areas under the standard normal curve, subtract the smaller area from the larger area to solve.
