Question

Transcribed Image Text:An engineering supervisor randomly measured the calorific value of a combustible
substance produced in a plant before and after the implementation of a quality
improvement policy. The following random measurements were obtained:
Before
8220
8096
7083
8852
8166
After
7762
7068
8437
8282
8822
Use the 0.05 level of significance to test whether the difference between the means
of these two samples is significant.
Instructions: Assume 8 = 0, in addressing the problem obtain the value of the test
statistic and its corresponding p – value up to four decimal places.
t%3D 0. 0221; р — value
