The length of a fully grown hibiscus plant is normally distributed and has a mean 35cm. It is found that 5% of these plants are longer than 45cm. Find the standard deviation σ. When plants are chosen for sale, those shorter than 30cm are rejected. Find the probability that a plant will be rejected. Please show the solution using standard normal table
