For 15 days, Roger tested the maximum level of his blood pressure (Systolic). His observations are as follows

\[\begin{array}{ | c | c | c | c | c |}
\hline 128 & 134 & 133 & 125 & 122 \\
\hline 137& 122& 120& 136& 134\\
\hline 132& 131& 128& 137& 129\\
\hline \end{array}\] By drawing its boxplot, answer the following

a) Roger wanted the median of his Systolic to be not more than 130. Did he achieve his goal?
b) Roger wanted the interquartile range of his Systolic to be less than 10. Did he achieve his goal?
c)If his Systolic on the 16th day was 126, does he achieve his goal for the median in (a)?

By drawing its boxplot, find

a) What is the length of boxplot from one end to other
b) By what common name do we know this length?
c) What is the Median?
d) What is the Interquartile range?
e) Is the lower whisker longer or shorter than the upper whisker, or are they exactly equal?
f) Is the median closer to the lower quartile, the upper quartile, or is it exactly midway?

In the adjacent boxplot, what is the range?

In the adjacent boxplot, what is the interquartile range (IQR)

In the adjacent boxplot, what percentage of scores are equal to or less than \(11\)?

In the adjacent boxplot, what percentage of scores are \(12\) or greater?

In the adjacent boxplot, are the scores \(7\) and \(14\) outliers?
