Chapter 11 – Question 24 (p. 351): At the .05 significance level‚ is the number of units produced on the night shift larger? H0: µ1 ≤ µ2 H1: µ1 > µ2 Z critical value: 1.645 x̄d (µ1): 351 x̄n (µ2): 345 σ^2d: 21 σ^2n: 28 Nd: 54 Nn: 60 Z=(351-345)/SQRT((28^2/60)+(21^2/54))=1.302 Fail to reject the null. Z is less than the critical value; therefore‚ the number of units produced on the night shift is less than the number of units produced on the day shift. Chapter 11 – Question
