Consider two identical iron nails: One nail is heated to 95 °C, the other is cooled to 15 °C. The two nails are placed in a coffee cup calorimeter and the system is allowed to come to thermal equilibrium. What is the final temperature of the two nails?
Step 2 - Transform the sample mean into a z-score (p. 133) x̅ = 26, N = 30, σ_X=6 Z = (X- µ)/(σ_X/√N) = (24- 26)/(6/5.4772) = (-2)/(1.0955) = 1.8257 Z = - 1.83 The z-score table notes that the area between the mean of 26 and the z-score of 1.83 = .46...
Darned old Foofy! Foofy computes the x̅ (MEAN) from data that her professor says is a random sample from population Q. she correctly computes that this mean has a z-score of +41 on the sampling distribution for population Q. Foofy claims she has proven that this could not...
