Question

Use the information given below to answer the next three questions. February 14, 2006, marked the 60th anniversary of ENIAC, the first computer in the world. In a Computerworld magazine interview, ENIAC's inventor Pres Eckert explains how they chose the right type of wires back in 1946: "We only used wire that passed the mouse test". They threw a number of wire samples in a cage full of hungry mice and let them eat the insulation, in order to determine which insulation type mice liked the least. ANOVA results with amounts of insulation (in mg) eaten by the mice are shown below. Test at the 0.10 level the claim that mice have different preferences among insulation types.
