An important feature of tablets is battery life, the number of hours before the battery needs to be recharged. The data shown in the table below contain the battery life of 10 WiFi-only and 10 3G/4G/WiFI 9- through 12-inch tablets. Complete parts (a) through (c). WiFi-only 3G/4G/WIFI 41 21 32 38 40 69 60 56 54 52 46 27 40 58 52 23 38 36 41 70 a. Assuming that the population variances from both types of tablets are equal, is there evidence of a difference in the mean battery life between the two types of tablets? Use a = 0.02. Let u, be the mean battery life for WiFi-only tablets and 2 be the mean battery life for 3G/4G/WiFi tablets. Determine the hypotheses. Choose the correct answer below. O A. HO: H1 = H2 OB. HO: H1 SH2 H1:141 # 142 H1: 141 > H42 O C. Ho: H1 2 H2 OD. HO:Hy # H2 Incorrect H1: 14
