A pavement engineer is attempting to study the effect of adding polypropylene (PP) to<br>asphalt concrete. The engineer claims that PP can improve the strength of asphalt<br>concrete. Results of indirect tensile strength tests on asphalt concrete samples with and<br>without PP are shown in Table Q2. At the 0.05 significance level, conduct a suitable<br>statistical test to prove or disprove the engineer's claim.<br>
