1. The breaking strength (in MPa) of a material is tested under three temperatures (T1, T2, T3) and two pressure levels (P1, P2). Data:
T1P1: 50, 52
T1P2: 53, 55
T2P1: 48, 50
T2P2: 51, 52
T3P1: 46, 47
T3P2: 49, 50
Perform a two-way ANOVA to check for temperature and pressure effects at 5% significance.
