Jessica collected data on the number of pages in her mystery book collection. Below are numerical summaries from her findings.
Based on the relationship between the mean, standard deviation, minimum, and maximum, is it reasonable to believe that the distribution of the number of pages in Jessica’s mystery books is approximately Normal?
No, because the standard deviation is much smaller than the mean, a Normal approximation is not reasonable.
No, without information about the median and IQR, we cannot determine if these data are approximately Normally distributed.
No, there are less than 2 standard deviations from the mean to the minimum and from the mean to the maximum.
Yes, the standard deviation is smaller than the mean and the minimum is about 10 times the standard deviation.
Yes, the distances from the mean to minimum and from the mean to the maximum are both about 3 standard deviations.
