Ontario is the Canadian centre for solar panel manufacturing, with companies like Canadian Solar exporting around the world. A competing company manufactures 250 watt solar panels, but the manufacturing process does not guarantee that the panels will produce exactly 250 watts of electric power. Some 8.5% of panels are classified as “underpowered,” producing less than 240 watts and can be sold, but for a lower price. The company improves its manufacturing process with the aim of reducing the percentage of underpowered panels from 8.5% to 4%. Workers take a random sample of 200 panels and find that 4.3% of them are under 240 watts. They wish to conduct a statistical test, at the 10% significance level, to establish whether the proportion of underpowered panels has been reduced. Calculate the power of the test assuming that the true proportion after the improvement in the manufacturing process is 0.04. (You are not asked to actually conduct the test.)
