Question

The weight of bicycles in a particular store is normally distributed with a standard deviation of 2.2 kg and average weight of 15 kg. Calculate the probability that a randomly selected bike from the store weighs over 20 kg.

Answer 1

To calculate the probability that a randomly selected bike from the store weighs over 20 kg, we need to calculate the z-score of 20 kg using the formula z = (x - µ) / σ.

Step-by-step explanation:

To calculate the probability that a randomly selected bike from the store weighs over 20 kg, we need to calculate the z-score of 20 kg using the formula z = (x - μ) / σ, where x is the value we want to find the probability for, μ is the average weight, and σ is the standard deviation.
