1.Two new work designs are under consideration for possible adoption in an assembly plant. A time study is conducted with 10 workers using design 1 and 12 workers using design 2. The means and standard deviations of their assembly times in minutes are shown below.

Design 1 Design 2

Mean 78.3 minutes 85.6 minutes

Std Deviation 4.8 minutes 6.5 minutes

Is the mean assembly time significantly higher for work design 2? Test at the 5% level of significance.

Expert Solution

(1) Null and Alternative Hypotheses

H0: The mean assembly time significantly not higher for work design 2

H1: The mean assembly time significantly higher for work design 2
