2. Battery Level of Laptop Computers in Shipment A computermanufacturer ships laptop computers with the batteries fullycharged so that customers can begin to use their purchases rightout of the box. In its last model, 85% of customers received fullycharged batteries. To simulate arrivals, the company shipped 100new model laptops (randomly picked from their warehouse) to variouscompany sites around the country. Of 100 laptops shipped, 96 ofthem arrived reading 100% charged. Do the data provide evidencethat the proportion of new model laptop computers arrived fullycharged to various company sites around the country of a computermanufacturer is higher than the last model?
