WebNov 28, 2024 · In this article, we will discuss how to plot normal distribution over Histogram in the R Programming Language. In a random dataset, it is generally observed that the distribution of data is normal i.e. on its visualization using density plot with the value of the variable in the x-axis and y-axis we get a bell shape curve. WebOct 3, 2024 · Step 1: Sketch a normal distribution with a mean of μ=30 lbs and a standard deviation of σ = 5 lbs. Step 2: A weight of 35 lbs is one standard deviation above the mean. Add the percentages above that point in the normal distribution. 13.5% + 2.35% + 0.15% = 16%. Step 3: Since there are 200 otters in the colony, 16% of 200 = 0.16 * 200 = 32.
