### Question:
ConfidenceInterval extends Interval<Double> { public Double getPointEstimate() { return d_pointEstimate; } ConfidenceInterval(Double pointEstimate, Double lowerBound, Double upperBound); Double getPointEstimate(); @Override boolean equals(Object o); @Override int hashCode(); @Override String toString();  }### Answer:
@Test public void testGetPointEstimate() { ConfidenceInterval ci1 = new ConfidenceInterval(1.044, 0.0, 2.0); assertEquals(1.044, ci1.getPointEstimate(), 0.00000001); }
