Resting heart rates, in beats per minute, were recorded for two samples of people. One sample was from people in the age group of 20 years to 30 years, and the other sample was from people in the age-group of 40 years to 50 years. The five-number summaries are shown in the table. Age group Minimum Q1 Median Q3 Maximum
20 to 30 60 71 72 75 84
40 to 50 60 70 73 76 85

The values of 60, 62, and 84 were common to both samples. The three values are identified as outliers with respect to the age-group 20 years to 30 years because they are either 1.5 times the interquartile range (IQR) greater than the upper quartile or 1.5 times the IQR less than the lower quartile. Using the same method for identifying outliers, which of the three values are identified as outliers for the age-group 40 years to 50 years.

a. None of the three values is identified as an outller.
b. Only 60 is identified as an outlier.
c. Only 60 and 62 are identified as outliers.
d. Only 60 and 84 are identified as outliers.
e. The three values are all identified as outliers.
