8.2 A study on breeding birds collects information such as the length oftheir eggs (in mm). Assume that the length is normally distributed with = 42.1 mmand o2 = 20.82. What is the probability of(a) finding an egg with a length greater than 50 mm?(b) finding an egg between 30 and 40 mm in length?Calculate the results both manually and by using R.

Given Information: Mean μ=42.1 Standard deviation σ=20.8
