One of the significant features of camera is battery life as measured by number of shots taken until battery needs to be recharged. Data at left contain battery life of 31 subcompact cameras and 15 compact cameras. Suppose that population variances from both kinds of digital cameras are equal, is there evidence of difference in mean battery life between two kinds of digital cameras at 0.05 level of significance.
