Normal density curves definition
WebTheir density curves will all look bell shaped, the function for their density curve will have the same form but they’ll have different values of µ and σ. We will see shortly what that does when we graph the curves. Definition 5. Family of Normal Distributions The set of all normal distributions (with every combination of µ and σ). WebA normal distribution curve is plotted along a horizontal axis labeled, Trunk Diameter in centimeters, which ranges from 60 to 240 in increments of 30. The curve rises from the horizontal axis at 60 with increasing steepness to its peak at 150, before falling with …

WebProblem 2: The graph would be left-skewed since the mean is smaller than the median and hence to the "left". Problem 3: Using similar logic as problem 1, the mode is the peak of the density curve. Since the median is the "middle number" and it's equal to the mode, the mode would also be in the middle of the graph.
