A study was carried out to investigate the height of a new maize genotype. It was found that the height of this particular genotype can be well approximated with a normal distribution with a mean of 2.2 m and a standard deviation of 0.2 m. For a randomly chosen maize plant in a field where only this genotype was planted, what is the probability that the plant’s height is:
i. Between 2.15m and 2.25 m?
ii. Between 2 m and 2.4 m?
iii. More than 2.3 m?
iv. Exactly equal to 2.2 m?
