The data shown below is collected from a sample. 8.5, 8.9, 8.8, 9.1, 8.2, 8.0, 9.0, 8.6, 8.4, 8.3, 8.2 To determine how much the sample mean differs from the population mean of 8.5, a student calculates the t-value. The student incorrectly calculates the t-value using the steps shown below. Step 1: 1 = 8.5+8.948.819.178.2+8.0+9.0+8.6+8.478.378.2 8.5455 Step 2: S2 = 1o (1.327273) = 0.1327273 = 11 = Step 3: t= 8.5455-8.5 = 1.08 0.1327273, 1 10 In which step did the student make the first error, and what is the correct expression for it? Step 2: S2 = 1 (1.327273) = 0.12067 Step 2: S = 1 (1.327273) = 0.1327273 = Step 3: t = - 8.5455 8.5 0.1327273 11 0.41 8.54558.5 Step 3: t= 1.14 0.1327273 /
