The mean of a normal distribution curve defines the location of the peak. On a graph, increasing the mean shifts the entire curve to the right on th x-axis, while decreasing the mean shifts the entire curve to the left.
Waterview has a mean of 13 rainy days while
Riverton has a mean of 11 rainy days
Since Waterview has a bigger mean than Riverton, then
Waterviews graph will have a peak farther to the right
The standard deviation of a normal distribution determines the width or spread of a bell curve. The larger the standard deviation, the wider the graph.
Waterview has a standard deviation of 2days and
Riverton has a standard deviation of 3days
Since Waterview has a smaller standard deviation than Riverton, then
Waterviews graph will have a peak that is narrower
