Over roughly the past 100years, the mean monthly April precipitation in a certain town equaled 3.1 inches with a standard deviation of 1.6 inches
Of the 119 measurements of April precipitation onrecord, 66.5% fell withinone, 97.5% withintwo, and99.1% within three standard deviations of the mean. Do you think that the distribution of April precipitation is approximatelynormal? Why or whynot?
A.
This distribution is likely approximately normal as these percentages increase the further from the mean they represent. This matches the characteristics of a normal distribution.
B.
This distribution is likely approximately normal as these percentages are similar to percentages within1, 2, or 3 standard deviations for the normal distribution.
C.
This distribution is not approximately normal as all measurements are the same distance from the mean for a normal distribution.
D.
This distribution is not approximately normal as the standard deviation is greater than 1.
