Give only typing answer with explanation and conclusion The melting points of two alloys are being compared. Thirty-five specimens of alloy 1 were cast. The average melting temperature was 517.0 *F and the standard deviation was 2.4 T. Forty-seven specimens of alloy 2 were cast. The average temperature was 515.1°7 and the standard deviation was it was 2.1°F. Is there a significant difference between the average temperatures of the two melting points of the two alloys? Use a = 1%
