Web31 mei 2024 · There are several reasons why the normal distribution is crucial in statistics. Some of those are as follows: 1. The statistical hypothesis test assumes that the data follows a normal distribution. 2. Both linear and non-linear regression assumes that the residual follows the normal distribution. 3. Web3 okt. 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.
