### Question:
Boxplot { public InterquatileRange innerFences() { return fences(1.5); } Boxplot(Double[] values);  Boxplot(Collection<Double> values);  Boxplot(double[] values); double median(); double q1(); double q3(); InterquatileRange innerFences(); InterquatileRange outerFences(); InterquatileRange fences(double m); double[] getValues(); double[] getValues(InterquatileRange fence); double[] filter(Predicate<Double> p);  }### Answer:
@Test public void testInnerFences() { Boxplot.InterquatileRange interquatileRange = this.boxplot .innerFences(); assertEquals(Double.valueOf(67.75), Double.valueOf(interquatileRange.getLower())); assertEquals(Double.valueOf(73.75), Double.valueOf(interquatileRange.getUpper())); }
