a. In a classic example the student in an Engineering Mathematics class argue that the volume of water contained in the wiper reservoir of the Mazda Mantis brand of car was not 0.25 liter whilst some of the student said the volume was more. To test the volume of the wiper reservoir of Mazda Mantis, some students with this brand of car brought their cars to the University's mechanical workshop where the volume of the wiper reservoirs were measured by the Mechanical Instructor. The mean was u = 0.22 and standard deviation o = 0.09. If 25 students brought their cars to the mechanical workshop, what conclusion did they reach at 5% level of significance?

a. In a classic example the student in an Engineering Mathematics class argue that the
volume of water contained in the wiper reservoir of the Mazda Mantis brand of car was
not 0.25 liter whilst some of the student said the volume was more. To test the volume
of the wiper reservoir of Mazda Mantis, some students with this brand of car brought
their cars to the University's mechanical workshop where the volume of the wiper
reservoirs were measured by the Mechanical Instructor. The mean was µ = 0.22 and
standard deviation o = 0.09. If 25 students brought their cars to the mechanical
workshop, what conclusion did they reach at 5% level of significance?
