A photoconductor film is manufactured at a nominal thickness of 0.65 mm. The product engineer wishes to increase the mean speed of the film and believes that this can be achieved by reducing the thickness of the film to 0.5 mm. Eight samples of each film thickness are manufactured in a pilot production process, and the film speed (in microjoules per square cm) is measured. For the 0.65mm film, the sample data result is X, =0.03 and sl = 0.0028, and for the 0.5 mm film the data yield X, = 0.028 and s2 0.0023. Note that an increase in film speed would lower the value of the observation in microjoules per square cm. a) Test Ho: o1 =02 versus H1:01 #02 using a = 0.02. %3D
