question 91

Short Answer

Explain the Role of Area in the Normal Density Function
-The weight of 2-year old hyraxes is known to be normally distributed with mean $\mu = 2200$ grams and standard deviation $\sigma = 365$ grams
(a) Draw a normal curve with the parameters labeled.
(b) Shade the region that represents the proportion of hyraxes who weighed more than 2930 grams.
(c) Suppose the area under the normal curve to the left of $X = 2930$ is $0.0228$ . Provide two interpretations of this result.
