Unformatted text preview: down to 60. The standard deviation of the pulse rates for this group of women are 12.4986. d. [2 pts] Are there any outliers in this data set? (Show work) IQR=80-68=12 LF=68-1.5(12)=50 UF=80+1.5(12)=98 So 124 is the outliner. e. [3 pts] Construct a boxplot for the data.

Yes, I would expect on mean. Because it is a right shewed, and the mean is higher than the median. h. [2 pts] Summarize your findings by describing the shape, center, spread, and unusual features of the data. The data is right skewed with a median pulse rate of 74 and IQR of 12. There was an outlier of 124....
