Question

Electrobat, a battery manufacturer, is investigating how storage temperature affects the performance of one of its popular deep-cell battery models used in recreational vehicles. Samples of 30 fully charged batteries were subjected to a light load under each of four different storage temperature levels. The hours until deep discharge (meaning ≤ 20% of charge remaining) were measured. The data is shown in the accompanying table.

0 degrees F (hrs to discharge)	30 degrees F (hrs to discharge)	60 degrees F (hrs to discharge)	90 degrees F (hrs to discharge)
